Misko Hevery 70f1e2e04a refactor(core): Create `TNodeType.Text` to display full template in `TView` debug (#39233)
When looking at `TView` debug template only Element nodes were displayed
as `TNode.Element` was used for both `RElement` and `RText`.
Additionally no text was stored in `TNode.value`. The result was that
the whole template could not be reconstructed. This refactoring creates
`TNodeType.Text` and store the text value in `TNode.value`.

The refactoring also changes `TNodeType` into flag-like structure make
it more efficient to check many different types at once.

Misko Hevery ca11ef2376 fix(core): Store ICU state in `LView` rather than in `TView` (#39233)
Before this refactoring/fix the ICU would store the current selected

Andrew Kushnir cb05c0102f fix(core): move generated i18n statements to the `consts` field of ComponentDef (#38404)
This commit updates the code to move generated i18n statements into the `consts` field of
ComponentDef to avoid invoking `$localize` function before component initialization (to better
support runtime translations) and also avoid problems with lazy-loading when i18n defs may not
be present in a chunk where it's referenced.

Prior to this change the i18n statements were generated at the top leve:

```
var I18N_0;
if (typeof ngI18nClosureMode !== "undefined" && ngI18nClosureMode) {
    var MSG_X = goog.getMsg(“…”);
    I18N_0 = MSG_X;
} else {
    I18N_0 = $localize('...');
}

defineComponent({
    // ...
    template: function App_Template(rf, ctx) {
        i0.ɵɵi18n(2, I18N_0);
    }
});
```

This commit updates the logic to generate the following code instead:

```
defineComponent({
    // ...
    consts: function() {
        var I18N_0;
        if (typeof ngI18nClosureMode !== "undefined" && ngI18nClosureMode) {
            var MSG_X = goog.getMsg(“…”);
            I18N_0 = MSG_X;
        } else {
            I18N_0 = $localize('...');
        }
        return [
            I18N_0
        ];
    },
    template: function App_Template(rf, ctx) {
        i0.ɵɵi18n(2, 0);
    }
});
```

Also note that i18n template instructions now refer to the `consts` array using an index
(similar to other template instructions).

Paul Gschwendtner 1601ee6f6a refactor(dev-infra): ng_rollup_bundle rule should leverage `@bazel/rollup` (#37623)
Refactors the `ng_rollup_bundle` rule to a macro that relies on
the `@bazel/rollup` package. This means that the rule no longer
deals with custom ESM5 flavour output, but rather only builds
prodmode ES2015 output. This matches the common build output
in Angular projects, and optimizations done in CLI where
ES2015 is the default optimization input.

The motiviation for this change is:

* Not duplicating rollup Bazel rules. Instead leveraging the official
rollup rule.
* Not dealing with a third TS output flavor in Bazel.The ESM5 flavour has the
potential of slowing down local development (as it requires compilation replaying)
* Updating the rule to be aligned with current CLI optimizations.

This also _fixes_ a bug that surfaced in the old rollup bundle rule.
Code that is unused, is not removed properly. The new rule fixes this by
setting the `toplevel` flag. This instructs terser to remove unused
definitions at top-level. This matches the optimization applied in CLI
projects. Notably the CLI doesn't need this flag, as code is always
wrapped by Webpack. Hence, the unused code eliding runs by default.

crisbeto ab3f4c9fe1 fix(core): infinite loop if injectable using inheritance has a custom decorator (#37022)
If we detect that an injectable class is inheriting from another injectable, we generate code that looks something like this:

```
const baseFactory = ɵɵgetInheritedFactory(Child);

@Injectable()
class Parent {}

@Injectable()
class Child extends Parent {
  static ɵfac = (t) => baseFactory(t || Child)
}
```

This usually works fine, because the `ɵɵgetInheritedFactory` resolves to the factory of `Parent`, but the logic can break down if the `Child` class has a custom decorator. Custom decorators can return a new class that extends the original once, which means that the `ɵɵgetInheritedFactory` call will now resolve to the factory of the `Child`, causing an infinite loop.

These changes fix the issue by changing the inherited factory resolution logic so that it walks up the prototype chain class-by-class, while skipping classes that have the same factory as the class that was passed in.

Fixes #35733.

Paul Gschwendtner 5615928df9 build: no longer run tslint from within gulp task (#35800)
Switches our tslint setup to the standard `tslint.json` linter excludes.
The set of files that need to be linted is specified through a Yarn script.

For IDEs, open files are linted with the closest tslint configuration, if the
tslint IDE extension is set up, and the source file is not excluded.

We cannot use the language service plugin for tslint as we have multiple nested
tsconfig files, and we don't want to add the plugin to each tsconfig. We
could reduce that bloat by just extending from a top-level tsconfig that
defines the language service plugin, but unfortunately the tslint plugin does
not allow the use of tslint configs which are not part of the tsconfig project.

This is problematic since the tslint configuration is at the project root, and we
don't want to copy tslint configurations next to each tsconfig file.

Additionally, linting of `d.ts` files has been re-enabled. This has been
disabled in the past and a TODO has been left. This commit fixes the
lint issues and re-enables linting.

Andrew Kushnir c013dd4ca6 fix(core): better handing of ICUs outside of i18n blocks (#35347)
Currently the logic that handles ICUs located outside of i18n blocks may throw exceptions at runtime. The problem is caused by the fact that we store incorrect TNode index for previous TNode (index that includes HEADER_OFFSET) and do not store a flag whether this TNode is a parent or a sibling node. As a result, the logic that assembles the final output uses incorrect TNodes and in some cases throws exceptions (when incompatible structure is extracted from tView.data due to the incorrect index). This commit adjusts the index and captures whether TNode is a parent to make sure underlying logic manipulates correct TNode.

Misko Hevery ee8b8f52aa feat(ivy): Change static priority resolution to be same level as directive it belongs to (#34938)
This change changes the priority order of static styling.

Current priority:
```
(least priority)
- Static
  - Component
  - Directives
  - Template
- Dynamic Binding
  - Component
    - Map/Interpolation
    - Property
  - Directives
    - Map/Interpolation
    - Property
  - Template
    - Map/Interpolation
    - Property
(highest priority)
```

The issue with the above priority is this use case:

```
<div style="color: red;" directive-which-sets-color-blue>
```
In the above case the directive will win and the resulting color will be `blue`. However a small change of adding interpolation to the example like so. (Style interpolation is coming in https://github.com/angular/angular/pull/34202)
```
<div style="color: red; width: {{exp}}px" directive-which-sets-color-blue>
```
Changes the priority from static binding to interpolated binding which means now the resulting color is `red`. It is very surprising that adding an unrelated interpolation and style can change the `color` which was not changed. To fix that we need to make sure that the static values are associated with priority of the source (directive or template) where they were declared. The new resulting priority is:

```
(least priority)
- Component
  - Static
  - Map/Interpolation
  - Property
- Directives
  - Static
  - Map/Interpolation
  - Property
- Template
  - Static
  - Map/Interpolation
  - Property

Miško Hevery 9bd9590767 refactor(ivy): change styling to use programmatic API on updates (#34804)
Previously we would write to class/style as strings `element.className` and `element.style.cssText`. Turns out that approach is good for initial render but not good for updates. Updates using this approach are problematic because we have to check to see if there was an out of bound write to style and than perform reconciliation. This also requires the browser to bring up CSS parser which is expensive.

Another problem with old approach is that we had to queue the DOM writes and flush them twice. Once on element advance instruction and once in `hostBindings`. The double flushing is expensive but it also means that a directive can observe that styles are not yet written (they are written after directive executes.)

The new approach uses `element.classList.add/remove` and `element.style.setProperty/removeProperty` API for updates only (it continues to use `element.className` and `element.style.cssText` for initial render as it is cheaper.) The other change is that the styling changes are applied immediately (no queueing). This means that it is the instruction which computes priority. In some circumstances it may result in intermediate writes which are than overwritten with new value. (This should be rare)

Overall this change deletes most of the previous code and replaces it with new simplified implement. The simplification results in code savings.

Miško Hevery 5aabe93abe refactor(ivy): Switch styling to new reconcile algorithm (#34616)
NOTE: This change must be reverted with previous deletes so that it code remains in build-able state.

This change deletes old styling code and replaces it with a simplified styling algorithm.

The mental model for the new algorithm is:
- Create a linked list of styling bindings in the order of priority. All styling bindings ere executed in compiled order and than a linked list of bindings is created in priority order.
- Flush the style bindings at the end of `advance()` instruction. This implies that there are two flush events. One at the end of template `advance` instruction in the template. Second one at the end of `hostBindings` `advance` instruction when processing host bindings (if any).
- Each binding instructions effectively updates the string to represent the string at that location. Because most of the bindings are additive, this is a cheap strategy in most cases. In rare cases the strategy requires removing tokens from the styling up to this point. (We expect that to be rare case)S Because, the bindings are presorted in the order of priority, it is safe to resume the processing of the concatenated string from the last change binding.

Miško Hevery 2961bf06c6 refactor(ivy): move `hostVars`/`hostAttrs` from instruction to `DirectiveDef` (#34683)
This change moves information from instructions to declarative position:
- `ɵɵallocHostVars(vars)` => `DirectiveDef.hostVars`
- `ɵɵelementHostAttrs(attrs)` => `DirectiveDef.hostAttrs`

When merging directives it is necessary to know about `hostVars` and `hostAttrs`. Before this change the information was stored in the `hostBindings` function. This was problematic, because in order to get to the information the `hostBindings` would have to be executed. In order for `hostBindings` to be executed the directives would have to be instantiated. This means that the directive instantiation would happen before we had knowledge about the `hostAttrs` and as a result the directive could observe in the constructor that not all of the `hostAttrs` have been applied. This further complicates the runtime as we have to apply `hostAttrs` in parts over many invocations.

`ɵɵallocHostVars` was unnecessarily complicated because it would have to update the `LView` (and Blueprint) while existing directives are already executing. By moving it out of `hostBindings` function we can access it statically and we can create correct `LView` (and Blueprint) in a single pass.

This change only changes how the instructions are generated, but does not change the runtime much. (We cheat by emulating the old behavior by calling `ɵɵallocHostVars` and `ɵɵelementHostAttrs`) Subsequent change will refactor the runtime to take advantage of the static information.

Misko Hevery 76698d38f7 refactor(ivy): Add style reconciliation algorithm (#34004)
This change introduces class/style reconciliation algorithm for DOM elements.
NOTE: The code is not yet hooked up, it will be used by future style algorithm.

Background:
Styling algorithm currently has [two paths](https://hackmd.io/@5zDGNGArSxiHhgvxRGrg-g/rycZk3N5S)
when computing how the style should be rendered.
1. A direct path which concatenates styling and uses `elemnent.className`/`element.style.cssText` and
2. A merge path which uses internal data structures and uses `element.classList.add/remove`/`element.style[property]`.

The situation is confusing and hard to follow/maintain. So a future PR will remove the merge-path and do everything with
direct-path. This however breaks when some other code adds class or style to the element without Angular's knowledge.
If this happens instead of switching from direct-path to merge-path algorithm, this change provides a different mental model
whereby we always do `direct-path` but the code which writes to the DOM detects the situation and reconciles the out of bound write.

The reconciliation process is as follows:
1. Detect that no one has modified `className`/`cssText` and if so just write directly (fast path).
2. If out of bounds write did occur, switch from writing using `className`/`cssText` to `element.classList.add/remove`/`element.style[property]`.
   This does require that the write function computes the difference between the previous Angular expected state and current Angular state.
   (This requires a parser. The advantage of having a parser is that we can support `style="width: {{exp}}px" kind of bindings.`)
   Compute the diff and apply it in non destructive way using `element.classList.add/remove`/`element.style[property]`

Properties of approach:
- If no out of bounds style modification:
  - Very fast code path: Just concatenate string in right order and write them to DOM.
  - Class list order is preserved
- If out of bounds style modification detected:
  - Penalty for parsing
  - Switch to non destructive modification: `element.classList.add/remove`/`element.style[property]`
  - Switch to alphabetical way of setting classes.

The `ModuleWithProviders` type has an optional type parameter that
should be specified to indicate what NgModule class will be provided.
This enables the Ivy compiler to statically determine the NgModule type
from the declaration files. This type parameter will become required in
the future, however to aid in the migration the compiler will detect
code patterns where using `ModuleWithProviders` as return type is
appropriate, in which case it transforms the emitted .d.ts files to
include the generic type argument.

This should reduce the number of occurrences where `ModuleWithProviders`
is referenced without its generic type argument.

When debugging `LView`s it is easy to get lost since all of them have
the same name. This change does three things:

1. It makes `TView` have an explicit type:
  - `Host`: for the top level `TView` for bootstrap
  - `Component`: for the `TView` which represents components template
  - `Embedded`: for the `TView` which represents an embedded template
2. It changes the name of `LView` to `LHostView`, `LComponentView`, and
  `LEmbeddedView` depending on the `TView` type.
3. For `LComponentView` and `LEmbeddedView` we also append the name of
  of the `context` constructor. The result is that we have `LView`s which
  are name as: `LComponentView_MyComponent` and `LEmbeddedView_NgIfContext`.

The above changes will make it easier to understand the structure of the
application when debugging.

NOTE: All of these are behind `ngDevMode` and will get removed in
production application.
