crisbeto 22786c8e88 fix(ivy): incorrectly generating shared pure function between null and object literal (#35481)
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.

Kristiyan Kostadinov 9228d7f15d perf(ivy): remove unused event argument in listener instructions (#35097)
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.

George Kalpakas fde89156fa fix(ngcc): correctly detect outer aliased class identifiers in ES5 (#35527)
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 () { ... }());
```

Paul Gschwendtner 8e12707f88 build: remove dependency on `@types/chokidar` (#35371)
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.

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 b9b512f729 fix(ivy): `LFrame` needs to release memory on `leaveView()` (#35156)
Root cause is that for perf reasons we cache `LFrame` so that we don't have to allocate it all the time. To be extra fast we clear the `LFrame` on `enterView()` rather that on `leaveView()`. The implication of this strategy is that the deepest `LFrame` will retain objects until the `LFrame` allocation depth matches the deepest object.

The fix is to simply clear the `LFrame` on `leaveView()` rather then on `enterView()`

Keen Yee Liau 81241af7ac fix(language-service): Suggest ? and ! operator on nullable receiver (#35200)
Under strict mode, the language service fails to typecheck nullable
symbols that have already been verified to be non-null.

This generates incorrect (false positive) and confusing diagnostics
for users.

To work around this issue in the short term, this commit changes the
diagnostic message from an error to a suggestion, and prompts users to
use the safe navigation operator (?) or non-null assertion operator (!).

For example, instead of

```typescript
{{ optional && optional.toString() }}
```

the following is cleaner:

```typescript
{{ optional?.toString() }}
{{ optional!.toString() }}
```

Note that with this change, users who legitimately make a typo in their
code will no longer see an error. I think this is acceptable, since
false positive is worse than false negative. However, if users follow
the suggestion, add ? or ! to their code, then the error will be surfaced.
This seems a reasonable trade-off.

ayazhafiz a92d97cda7 fix(compiler): report errors for missing binding names (#34595)
Currently, would-be binding attributes that are missing binding names
are not parsed as bindings, and fall through as regular attributes. In
some cases, this can lead to a runtime error; trying to assign `#` as a
DOM attribute in an element like in `<div #></div>` fails because `#` is
not a valid attribute name.

Attributes composed of binding prefixes but not defining a binding
should be considered invalid, as this almost certainly indicates an
unintentional elision of a binding by the developer. This commit
introduces error reporting for attributes with a binding name prefix but
no actual binding name.

JoostK 5de5b52beb fix(ivy): repeat template guards to narrow types in event handlers (#35193)
In Ivy's template type checker, event bindings are checked in a closure
to allow for accurate type inference of the `$event` parameter. Because
of the closure, any narrowing effects of template guards will no longer
be in effect when checking the event binding, as TypeScript assumes that
the guard outside of the closure may no longer be true once the closure
is invoked. For more information on TypeScript's Control Flow Analysis,
please refer to https://github.com/microsoft/TypeScript/issues/9998.

In Angular templates, it is known that an event binding can only be
executed when the view it occurs in is currently rendered, hence the
corresponding template guard is known to hold during the invocation of
an event handler closure. As such, it is desirable that any narrowing
effects from template guards are still in effect within the event
handler closure.

This commit tweaks the generated Type-Check Block (TCB) to repeat all
template guards within an event handler closure. This achieves the
narrowing effect of the guards even within the closure.

Alex Rickabaugh 3c69442dbd feat(compiler-cli): implement NgTscPlugin on top of the NgCompiler API (#34792)
This commit implements an experimental integration with tsc_wrapped, where
it can load the Angular compiler as a plugin and perform Angular
transpilation at a user's request.

This is an alternative to the current ngc_wrapped mechanism, which is a fork
of tsc_wrapped from several years ago. tsc_wrapped has improved
significantly since then, and this feature will allow Angular to benefit
from those improvements.

Currently the plugin API between tsc_wrapped and the Angular compiler is a
work in progress, so NgTscPlugin does not yet implement any interfaces from
@bazel/typescript (the home of tsc_wrapped). Instead, an interface is
defined locally to guide this standardization.
