* it's tricky to get out of the runfiles tree with `bazel test` as `BUILD_WORKSPACE_DIRECTORY` is not set but I employed a trick to read the `DO_NOT_BUILD_HERE` file that is one level up from `execroot` and that contains the workspace directory. This is experimental and if `bazel test //:test.debug` fails than `bazel run` is still guaranteed to work as `BUILD_WORKSPACE_DIRECTORY` will be set in that context
* test //integration:bazel_test and //integration:bazel-schematics_test exclusively
* run "exclusive" and "manual" bazel-in-bazel integration tests in their own CI job as they take 8m+ to execute

@babel/core dep had to be pinned to 7.6.4 or else //packages/localize/src/tools/test:test failed. Also //packages/localize uses @babel/generator, @babel/template, @babel/traverse & @babel/types so these deps were added to package.json as they were not being hoisted anymore from @babel/core transitive.

When a pipe inherits its constructor, and as a result its factory, from an injectable in AOT mode, it can end up throwing an error, because the inject implementation hasn't been set yet. These changes ensure that the implementation is set before the pipe's factory is invoked.
Note that this isn't a problem in JIT mode, because the factory inheritance works slightly differently, hence why this test isn't going through `TestBed`.
Fixes#35277.

Under View Engine's default (non-fullTemplateTypeCheck) checking, object and
array literals which appear in templates are treated as having type `any`.
This allows a number of patterns which would not otherwise compile, such as
indexing an object literal by a string:
```html
{{ {'a': 1, 'b': 2}[value] }}
```
(where `value` is `string`)
Ivy, meanwhile, has always inferred strong types for object literals, even
in its compatibility mode. This commit fixes the bug, and adds the
`strictLiteralTypes` flag to specifically control this inference. When the
flag is `false` (in compatibility mode), object and array literals receive
the `any` type.
PR Close#35462
In its default compatibility mode, the Ivy template type-checker attempts to
emulate the View Engine default mode as accurately as is possible. This
commit addresses a gap in this compatibility that stems from a View Engine
type-checking bug.
Consider two template expressions:
```html
{{ obj?.field }}
{{ fn()?.field }}
```
and suppose that the type of `obj` and `fn()` are the same - both return
either `null` or an object with a `field` property.
Under View Engine, these type-check differently. The `obj` case will catch
if the object type (when not null) does not have a `field` property, while
the `fn()` case will not. This is due to how View Engine represents safe
navigations:
```typescript
// for the 'obj' case
(obj == null ? null as any : obj.field)
// for the 'fn()' case
let tmp: any;
((tmp = fn()) == null ? null as any : tmp.field)
```
Because View Engine uses the same code generation backend as it does to
produce the runtime code for this expression, it uses a ternary for safe
navigation, with a temporary variable to avoid invoking 'fn()' twice. The
type of this temporary variable is 'any', however, which causes the
`tmp.field` check to be meaningless.
Previously, the Ivy template type-checker in compatibility mode assumed that
`fn()?.field` would always check for the presence of 'field' on the non-null
result of `fn()`. This commit emulates the View Engine bug in Ivy's
compatibility mode, so an 'any' type will be inferred under the same
conditions.
As part of this fix, a new format for safe navigation operations in template
type-checking code is introduced. This is based on the realization that
ternary based narrowing is unnecessary.
For the `fn()` case in strict mode, Ivy now generates:
```typescript
(null as any ? fn()!.field : undefined)
```
This effectively uses the ternary operator as a type "or" operation. The
resulting type will be a union of the type of `fn()!.field` with
`undefined`.
For the `fn()` case in compatibility mode, Ivy now emulates the bug with:
```typescript
(fn() as any).field
```
The cast expression includes the call to `fn()` and allows it to be checked
while still returning a type of `any` from the expression.
For the `obj` case in compatibility mode, Ivy now generates:
```typescript
(obj!.field as any)
```
This cast expression still returns `any` for its type, but will check for
the existence of `field` on the type of `obj!`.

I think the bug is introduced in my PR#34847. For example, 'model="{{title}}"', the attribute value cannot be parsed by 'parseTemplateBindings'.

In ES5 code, TypeScript requires certain helpers (such as
`__spreadArrays()`) to be able to support ES2015+ features. These
helpers can be either imported from `tslib` (by setting the
`importHelpers` TS compiler option to `true`) or emitted inline (by
setting the `importHelpers` and `noEmitHelpers` TS compiler options to
`false`, which is the default value for both).
Ngtsc's `StaticInterpreter` (which is also used during ngcc processing)
is able to statically evaluate some of these helpers (currently
`__assign()`, `__spread()` and `__spreadArrays()`), as long as
`ReflectionHost#getDefinitionOfFunction()` correctly detects the
declaration of the helper. For this to happen, the left-hand side of the
corresponding call expression (i.e. `__spread(...)` or
`tslib.__spread(...)`) must be evaluated as a function declaration for
`getDefinitionOfFunction()` to be called with.
In the case of imported helpers, the `tslib.__someHelper` expression was
resolved to a function declaration of the form
`export declare function __someHelper(...args: any[][]): any[];`, which
allows `getDefinitionOfFunction()` to correctly map it to a TS helper.
In contrast, in the case of emitted helpers (and regardless of the
module format: `CommonJS`, `ESNext`, `UMD`, etc.)), the `__someHelper`
identifier was resolved to a variable declaration of the form
`var __someHelper = (this && this.__someHelper) || function () { ... }`,
which upon further evaluation was categorized as a `DynamicValue`
(prohibiting further evaluation by the `getDefinitionOfFunction()`).
As a result of the above, emitted TypeScript helpers were not evaluated
in ES5 code.
---
This commit changes the detection of TS helpers to leverage the existing
`KnownFn` feature (previously only used for built-in functions).
`Esm5ReflectionHost` is changed to always return `KnownDeclaration`s for
TS helpers, both imported (`getExportsOfModule()`) as well as emitted
(`getDeclarationOfIdentifier()`).
Similar changes are made to `CommonJsReflectionHost` and
`UmdReflectionHost`.
The `KnownDeclaration`s are then mapped to `KnownFn`s in
`StaticInterpreter`, allowing it to statically evaluate call expressions
involving any kind of TS helpers.

This is in preparation of using the `KnownFn` type for known TypeScript
helpers (in addition to built-in functions/methods). This will in turn
allow simplifying the detection of both imported and emitted TypeScript
helpers.

When statically evaluating CommonJS code it is possible to find that we
are looking for the declaration of an identifier that actually came from
a typings file (rather than a CommonJS file).
Previously, the CommonJS reflection host would always try to use a
CommonJS specific algorithm for finding identifier declarations, but
when the id is actually in a typings file this resulted in the returned
declaration being the containing file of the declaration rather than the
declaration itself.
Now the CommonJS reflection host will check to see if the file
containing the identifier is a typings file and use the appropriate
stategy.
(Note: This is the equivalent of #34356 but for CommonJS.)

In #33705 we made it so that we generate pure functions for object/array literals in order to avoid having them be shared across elements/views. The problem this introduced is that further down the line the `ContantPool` uses the generated literal in order to figure out whether to share an existing factory or to create a new one. `ConstantPool` determines whether to share a factory by creating a key from the AST node and using it to look it up in the factory cache, however the key generation function didn't handle function invocations and replaced them with `null`. This means that the key for `{foo: pureFunction0(...)}` and `{foo: null}` are the same.
These changes rework the logic so that instead of generating a `null` key
for function invocations, we generate a variable called `<unknown>` which
shouldn't be able to collide with anything.
Fixes#35298.

Currently Ivy always generates the `$event` function argument, even if it isn't being used by the listener expressions. This can lead to unnecessary bytes being generated, because optimizers won't remove unused arguments by default. These changes add some logic to avoid adding the argument when it isn't required.

In ES5 and ES2015, class identifiers may have aliases. Previously, the
`NgccReflectionHost`s recognized the following formats:
- ES5:
```js
var MyClass = (function () {
function InnerClass() {}
InnerClass_1 = InnerClass;
...
}());
```
- ES2015:
```js
let MyClass = MyClass_1 = class MyClass { ... };
```
In addition to the above, this commit adds support for recognizing an
alias outside the IIFE in ES5 classes (which was previously not
supported):
```js
var MyClass = MyClass_1 = (function () { ... }());

The top-menu items have both a `title` and a `tooltip` property. The
`title` is used as text content, so there is little point in using it as
"tooltip" (via the HTMLElement's `title` property) too.
This commit switches to using the `tooltip` property to populate the
`title`. Note that in many cases, the `tooltip` property is derived from
`title` anyway (so there is no practical change in behavior in these
cases).

We recently updated chokidar to `3.0.0`. The latest version of
chokidar provides TypeScript types on its own and makes the extra
dependency on the `@types` unnecessary.
This seems to have caused the `build-packages-dist` script to fail with
an error like:
```
[strictDeps] transitive dependency on external/npm/node_modules/chokidar/types/index.d.ts
not allowed. Please add the BUILD target to your rule's deps.
```
It's unclear why that happens, but a reasonable theory would be that
the TS compilation accidentally picked up the types from `chokidar`
instead of `@types/chokidar`, and the strict deps `@bazel/typescript`
check reported this as issue because it's not an explicit target dependency.
