`TypeScript` only supports merging and extending of `compilerOptions`. This is an implementation to support extending and inheriting of `angularCompilerOptions` from multiple files.

The bootstrap property of @NgModule was not previously compiled by
the compiler in AOT or JIT modes (in Ivy). This commit adds support
for bootstrap.

Closure requires @nocollapse on Ivy definition static fields in order
to not convert them to standalone constants. However tsickle, the tool
which would ordinarily be responsible for adding @nocollapse, doesn't
properly annotate fields which are added synthetically via transforms.
So this commit adds @nocollapse by applying regular expressions against
code during the final write to disk.

In tsc 3.0 the check that enables program structure reuse in tryReuseStructureFromOldProgram has changed
and now uses identity comparison on arrays within CompilerOptions. Since we recreate the options
on each incremental compilation, we now fail this check.
After this change the default set of options is reused in between incremental compilations, but we still
allow options to be overriden if needed.

This fixes a bug in ngtsc where each @Directive was compiled using a
separate ConstantPool. This resulted in two issues:
* Directive constants were not shared across the file
* Extra statements from directive compilation were dropped instead of
added to the file
This commit fixes both issues and adds a test to verify @Directive is
working properly.

Since non-flat module formats (esm2015, esm5) have different structure
than their flat counterparts (and since we are operating on JS files
inside `node_modules/`, we need to configure TS to include deeply nested
JS files (by specifying a sufficiently high `maxNodeModuleJsDepth`).
Remains to be determined if this has any (noticeable) performance
implications.
PR Close#25406
When generating the 'directives:' property of ngComponentDef, ngtsc
needs to be conscious of declaration order. If a directive being
written into the array is declarated after the component currently
being compiled, then the entire directives array needs to be wrapped
in a closure.
This commit fixes ngtsc to pay attention to such ordering issues
within directives arrays.
PR Close#25392
This commit creates an API for factory functions which allows them
to be inherited from one another. To do so, it differentiates between
the factory function as a wrapper for a constructor and the factory
function in ngInjectableDefs which is determined by a default
provider.
The new form is:
factory: (t?) => new (t || SomeType)(inject(Dep1), inject(Dep2))
The 't' parameter allows for constructor inheritance. A subclass with
no declared constructor inherits its constructor from the superclass.
With the 't' parameter, a subclass can call the superclass' factory
function and use it to create an instance of the subclass.
For @Injectables with configured providers, the factory function is
of the form:
factory: (t?) => t ? constructorInject(t) : provider();
where constructorInject(t) creates an instance of 't' using the
naturally declared constructor of the type, and where provider()
creates an instance of the base type using the special declared
provider on @Injectable.

Inside of a nested template, an attempt to generate code for a banana-
in-a-box expression would cause a crash in the _AstToIrVisitor, as it
was not handling the case where a write would be generated to a local
variable.
This change supports such a mode of operation.

To match the View Engine behavior.
We should make this configurable so that the node injector is tree shaken when
directives do not need to be published.

Previously the compiler compliance tests ran and built test code with
real dependencies on @angular/core and @angular/common. This meant that
any changes to the compiler would result in long rebuild processes
for tests to rerun.
This change removes those dependencies and causes test code to be built
against the fake_core stub of @angular/core that the ngtsc tests use.
This change also removes the dependency on @angular/common entirely, as
locality means it's possible to reference *ngIf without needing to link
to an implementation.
PR Close#25248
Existing bootstrap code in the wild depends on the existence of
.ngfactory files, which Ivy does not need. This commit adds the
capability in ngtsc to generate .ngfactory files which bridge
existing bootstrap code with Ivy.
This is an initial step. Remaining work includes complying with
the compiler option to specify a generated file directory, as well
as presumably testing in g3.
PR Close#25176
Before this change bound properties would not be used when matching directives
at runtime.
That is `<ng-template [ngIf]=cond>...</ng-template>` would not trigger the
`ngIf` directive.
PR Close#25272
Update XMB placeholders(<ph>) to include the original value on top of an
example. Placeholders can by definition have one example(<ex>) tag and a
text node. The text node is used by TC as the "original" value from the
placeholder, while the example should represent a dummy value.
For example: <ph name="PET"><ex>Gopher</ex>{{ petName }}</ph>.
This change makes sure that we have the original text, but it *DOES NOT*
make sure that the example is correct. The example has the same wrong
behavior of showing the interpolation text rather than a useful
example.
No breaking changes, but tools that depend on the previous behavior and
don't consider the full XMB definition may fail to parse the XMB.
