Used to resolve resource URLs on `@Component` when used with JIT compilation.
```
@Component({
selector: 'my-comp',
templateUrl: 'my-comp.html', // This requires asynchronous resolution
})
class MyComponnent{
}
// Calling `renderComponent` will fail because `MyComponent`'s `@Compenent.templateUrl`
// needs to be resolved because `renderComponent` is synchronous process.
// renderComponent(MyComponent);
// Calling `resolveComponentResources` will resolve `@Compenent.templateUrl` into
// `@Compenent.template`, which would allow `renderComponent` to proceed in synchronous manner.
// Use browser's `fetch` function as the default resource resolution strategy.
resolveComponentResources(fetch).then(() => {
// After resolution all URLs have been converted into strings.
renderComponent(MyComponent);
});

Previously the todo app imported reflect-metadata, since it is a dependency
of JIT and the todo app tests run in both JIT and AOT modes. However, the
code doesn't get tree-shaken away in AOT mode.
This change adds a target //packages/core/test/bundling/util:reflect_metadata
which, depending on whether the compile flag is in JIT or AOT mode, either
includes reflect-metadata or is a no-op.
Not including reflect-metadata gets the compressed todo bundle down to 12.5 kB.

ngtsc is sufficiently capable now that it can compile hello_world
and todo and achieve equivalent results to ngc in ivy (global) mode.
Bundle sizes:
hello_world - 3.0 kB
todo - 14.7 kB

This change makes @angular/compiler more tree-shakeable by changing
an enum to a const enum and by getting rid of a top-level map that
the tree-shaker was seeing as a reference which caused r3_identifiers
to be retained.
This drops a few hundred bytes of JS from tree-shaken ngtsc compiled
apps.

Previously the repo was depending on an old version of build optimizer.
This change updates to the latest (an RC release in the CLI package).
Additionally, this changes the behavior of ng_rollup_bundle to apply
the optimizer to ngtsc compiled code, and configures it to treat the
@angular/compiler package as side-effect-free.
This results in a substantial size reduction of ngtsc compiled code.

@angular/core is unique in that it defines the Angular decorators
(@Component, @Directive, etc). Ordinarily ngtsc looks for imports
from @angular/core in order to identify these decorators. Clearly
within core itself, this strategy doesn't work.
Instead, a special constant ITS_JUST_ANGULAR is declared within a
known file in @angular/core. If ngtsc sees this constant it knows
core is being compiled and can ignore the imports when evaluating
decorators.
Additionally, when compiling decorators ngtsc will often write an
import to @angular/core for needed symbols. However @angular/core
cannot import itself. This change creates a module within core to
export all the symbols needed to compile it and adds intelligence
within ngtsc to write relative imports to that module, instead of
absolute imports to @angular/core.

This commit takes advantage of the @angular/compiler work for ngInjectorDef

All errors for existing fields have been detected and suppressed with a
`!` assertion.
Issue/24571 is tracking proper clean up of those instances.
One-line change required in ivy/compilation.ts, because it appears that
the new syntax causes tsickle emitted node to no longer track their
original sourceFiles.

This change supports compilation of components, directives, and modules
within ngtsc. Support is not complete, but is enough to compile and test
//packages/core/test/bundling/todo in full AOT mode. Code size benefits
are not yet achieved as //packages/core itself does not get compiled, and
some decorators (e.g. @Input) are not stripped, leading to unwanted code
being retained by the tree-shaker. This will be improved in future commits.

PR Close#24479
At runtime in JIT mode, when the compiler writes a reference to a symbol that symbol
is resolved through a symbol table named angularCoreEnv in render3/jit/environment.
Previously, this symbol table was not kept up-to-date with the Ivy instruction set
and the names of symbols the compiler could reference.
This change brings the symbol table in sync, and also adds a test that verifies every
symbol the compiler can reference is available at runtime in the symbol table.

When creating content queries from a directive on an element we need to take into account
existing view queries. The same element can be reported to both content and view queries
so freshly created content queries must be combined with pre-existing view queries.

PR Close#24386
Previously, the transitive scopes of an NgModuleDef were computed
during execution of the @NgModule decorator. This meant that JIT-
compiled modules could only import other JIT-compiled modules, as
the import mechanism relied on the calculation of transitive scopes
to already have happened for the imported module.
This change moves computation of transitive scopes to a function
`transitiveScopesFor` (and makes it lazy). This opens the door for
AOT -> JIT or JIT -> AOT imports, as transitive scopes for AOT
modules can be calculated when needed by JIT, and AOT modules can
also write expressions that call `transitiveScopesFor` when
importing a JIT-compiled module.

Two new CircleCI environments are created: test_ivy_jit and test_ivy_aot.
Both run a subset of the tests that have been marked with Bazel tags as
being appropriate for that environment.
Once all the tests pass, builds are published to the *-builds repo both
for the legacy View Engine compiled code as well as for ivy-jit and ivy-aot.

if it can access the id.

`NgForOf` used to implement `OnChanges` and than use
`ngOnChanges` callback to detect when `ngForOf` binding
changed to update the differ. We now do the checking
manually which puts less pressure on the runtime to do
the bookkeeping and should result in minor perf improvement.
