`TNode.insertBeforeIndex` is only populated when i18n is present. This
change puts all code which reads `insertBeforeIndex` behind a

Misko Hevery 68d4de6770 refactor(core): Replace `ExpandoInstructions` with `HostBindingOpCodes` (#39301)
The `ExpandoInstructions` was unnecessarily convoluted way to solve the
problem of calling the `HostBindingFunction`s on components and
directives. The code was complicated and hard to fallow.

The replacement is a simplified way to achieve the same thing, which
is also more efficient in space and speed.

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

Greg Magolan 42a164f522 build: upgrade angular build, integration/bazel and @angular/bazel package to rule_nodejs 2.2.0 (#39182)
Updates to rules_nodejs 2.2.0. This is the first major release in 7 months and includes a number of features as well
as breaking changes.

Release notes: https://github.com/bazelbuild/rules_nodejs/releases/tag/2.0.0

Features of note for angular/angular:

* stdout/stderr/exit code capture; this could be potentially be useful

* TypeScript (ts_project); a simpler tsc rule that ts_library that can be used in the repo where ts_library is too
  heavy weight

Breaking changes of note for angular/angular:

* loading custom rules from npm packages: `ts_library` is no longer loaded from `@npm_bazel_typescript//:index.bzl`
  (which no longer exists) but is now loaded from `@npm//@bazel/typescript:index.bzl`

* with the loading changes above, `load("@npm//:install_bazel_dependencies.bzl", "install_bazel_dependencies")` is
  no longer needed in the WORKSPACE which also means that yarn_install does not need to run unless building/testing
  a target that depends on @npm. In angular/angular this is a minor improvement as almost everything depends on @npm.

* @angular/bazel package is also updated in this PR to support the new load location; Angular + Bazel users that
  require it for ng_package (ng_module is no longer needed in OSS with Angular 10) will need to load from
  `@npm//@angular/bazel:index.bzl`. I investigated if it was possible to maintain backward compatability for the old
  load location `@npm_angular_bazel` but it is not since the package itself needs to be updated to load from
  `@npm//@bazel/typescript:index.bzl` instead of `@npm_bazel_typescript//:index.bzl` as it depends on ts_library
  internals for ng_module.

* runfiles.resolve will now throw instead of returning undefined to match behavior of node require

Other changes in angular/angular:

* integration/bazel has been updated to use both ng_module and ts_libary with use_angular_plugin=true.
  The latter is the recommended way for rules_nodejs users to compile Angular 10 with Ivy. Bazel + Angular ViewEngine is
  supported with @angular/bazel <= 9.0.5 and Angular <= 8. There is still Angular ViewEngine example on rules_nodejs
  https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_view_engine on these older versions but users
  that want to update to Angular 10 and are on Bazel must switch to Ivy and at that point ts_library with
  use_angular_plugin=true is more performant that ng_module. Angular example in rules_nodejs is configured this way
  as well: https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular. As an aside, we also have an
  example of building Angular 10 with architect() rule directly instead of using ts_library with angular plugin:
  https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_bazel_architect.

NB: ng_module is still required for angular/angular repository as it still builds ViewEngine & @angular/bazel
also provides the ng_package rule. ng_module can be removed in the future if ViewEngine is no longer needed in
angular repo.

* JSModuleInfo provider added to ng_module. this is for forward compat for future rules_nodejs versions.

Andrew Scott d1415162cb fix(core): clear the `RefreshTransplantedView` when detached (#38768)
The `RefreshTransplantedView` flag is used to indicate that the view or one of its children
is transplanted and dirty, so it should still be refreshed as part of change detection.
This flag is set on the transplanted view itself as well setting a
counter on as its parents.
When a transplanted view is detached and still has this flag, it means
it got detached before it was refreshed. This can happen for "backwards
references" or transplanted views that are inserted at a location that
was already checked. In this case, we should decrement the parent
counters _and_ clear the flag on the detached view so it's not seen as
"transplanted" anymore (it is detached and has no parent counters to
adjust).

Bjarki f245c6bb15 fix(core): remove closing body tag from inert DOM builder (#38454)
Fix a bug in the HTML sanitizer where an unclosed iframe tag would
result in an escaped closing body tag as the output:

_sanitizeHtml(document, '<iframe>') => '&lt;/body&gt;'

This closing body tag comes from the DOMParserHelper where the HTML to be
sanitized is wrapped with surrounding body tags. When an opening iframe
tag is parsed by DOMParser, which DOMParserHelper uses, everything up
until its matching closing tag is consumed as a text node. In the above
example this includes the appended closing body tag.

By removing the explicit closing body tag from the DOMParserHelper and
relying on the body tag being closed implicitly at the end, the above
example is sanitized as expected:

Paul Gschwendtner ca07da4563 fix(core): detect DI parameters in JIT mode for downleveled ES2015 classes (#38463)
In the Angular Package Format, we always shipped UMD bundles and previously even ES5 module output.
With V10, we removed the ES5 module output but kept the UMD ES5 output.

For this, we were able to remove our second TypeScript transpilation. Instead we started only
building ES2015 output and then downleveled it to ES5 UMD for the NPM packages. This worked
as expected but unveiled an issue in the `@angular/core` reflection capabilities.

In JIT mode, Angular determines constructor parameters (for DI) using the `ReflectionCapabilities`. The
reflection capabilities basically read runtime metadata of classes to determine the DI parameters. Such
metadata can be either stored in static class properties like `ctorParameters` or within TypeScript's `design:params`.

If Angular comes across a class that does not have any parameter metadata, it tries to detect if the
given class is actually delegating to an inherited class. It does this naively in JIT by checking if the
stringified class (function in ES5) matches a certain pattern. e.g.

```js
function MatTable() {
  var _this = _super.apply(this, arguments) || this;
```

These patterns are reluctant to changes of the class output. If a class is not recognized properly, the
DI parameters will be assumed empty and the class is **incorrectly** constructed without arguments.

This actually happened as part of v10 now. Since we downlevel ES2015 to ES5 (instead of previously
compiling sources directly to ES5), the class output changed slightly so that Angular no longer detects
it. e.g.

```js
var _this = _super.apply(this, __spread(arguments)) || this;
```

This happens because the ES2015 output will receive an auto-generated constructor if the class
defines class properties. This constructor is then already containing an explicit `super` call.

```js
export class MatTable extends CdkTable {
    constructor() {
        super(...arguments);
        this.disabled = true;
    }
}
```

If we then downlevel this file to ES5 with `--downlevelIteration`, TypeScript adjusts the `super` call so that
the spread operator is no longer used (not supported in ES5). The resulting super call is different to the
super call that would have been emitted if we would directly transpile to ES5. Ultimately, Angular no
longer detects such classes as having an delegate constructor -> and DI breaks.

We fix this by expanding the rather naive RegExp patterns used for the reflection capabilities
so that downleveled pass-through/delegate constructors are properly detected. There is a risk
of a false-positive as we cannot detect whether `__spread` is actually the TypeScript spread
helper, but given the reflection patterns already make lots of assumptions (e.g. that `super` is
actually the superclass, we should be fine making this assumption too. The false-positive would
not result in a broken app, but rather in unnecessary providers being injected (as a noop).

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).

waterplea b071495f92 fix(core): fix multiple nested views removal from ViewContainerRef (#38317)
When removal of one view causes removal of another one from the same
ViewContainerRef it triggers an error with views length calculation. This commit
fixes this bug by removing a view from the list of available views before invoking
actual view removal (which might be recursive and relies on the length of the list
of available views).

Fixes #38201.

crisbeto a80f654af9 fix(core): error if CSS custom property in host binding has number in name (#38432)
Fixes an error if a CSS custom property, used inside a host binding, has a
number in its name. The error is thrown because the styling parser only
expects characters from A to Z,dashes, underscores and a handful of other
characters.

JoostK 9514fd9080 fix(compiler): evaluate safe navigation expressions in correct binding order (#37911)
When using the safe navigation operator in a binding expression, a temporary
variable may be used for storing the result of a side-effectful call.
For example, the following template uses a pipe and a safe property access:

```html
<app-person-view [enabled]="enabled" [firstName]="(person$ | async)?.name"></app-person-view>
```

The result of the pipe evaluation is stored in a temporary to be able to check
whether it is present. The temporary variable needs to be declared in a separate
statement and this would also cause the full expression itself to be pulled out
into a separate statement. This would compile into the following
pseudo-code instructions:

```js
var temp = null;
var firstName = (temp = pipe('async', ctx.person$)) == null ? null : temp.name;
property('enabled', ctx.enabled)('firstName', firstName);
```

Notice that the pipe evaluation happens before evaluating the `enabled` binding,
such that the runtime's internal binding index would correspond with `enabled`,
not `firstName`. This introduces a problem when the pipe uses `WrappedValue` to
force a change to be detected, as the runtime would then mark the binding slot
corresponding with `enabled` as dirty, instead of `firstName`. This results
in the `enabled` binding to be updated, triggering setters and affecting how
`OnChanges` is called.

In the pseudo-code above, the intermediate `firstName` variable is not strictly
necessary---it only improved readability a bit---and emitting it inline with
the binding itself avoids the out-of-order execution of the pipe:

```js
var temp = null;
property('enabled', ctx.enabled)
  ('firstName', (temp = pipe('async', ctx.person$)) == null ? null : temp.name);
```

This commit introduces a new `BindingForm` that results in the above code to be
generated and adds compiler and acceptance tests to verify the proper behavior.

JoostK 2e9fdbde9e fix(core): prevent NgModule scope being overwritten in JIT compiler (#37795)
In JIT compiled apps, component definitions are compiled upon first
access. For a component class `A` that extends component class `B`, the
`B` component is also compiled when the `InheritDefinitionFeature` runs
during the compilation of `A` before it has finalized. A problem arises
when the compilation of `B` would flush the NgModule scoping queue,
where the NgModule declaring `A` is still pending. The scope information
would be applied to the definition of `A`, but its compilation is still
in progress so requesting the component definition would compile `A`
again from scratch. This "inner compilation" is correctly assigned the
NgModule scope, but once the "outer compilation" of `A` finishes it
would overwrite the inner compilation's definition, losing the NgModule
scope information.

In summary, flushing the NgModule scope queue could trigger a reentrant
compilation, where JIT compilation is non-reentrant. To avoid the
reentrant compilation, a compilation depth counter is introduced to
avoid flushing the NgModule scope during nested compilations.

crisbeto 5dc8d287aa fix(core): queries not matching string injection tokens (#38321)
Queries weren't matching directives that provide themselves via string
injection tokens, because the assumption was that any string passed to
a query decorator refers to a template reference.

These changes make it so we match both template references and
providers while giving precedence to the template references.
