`ngcc` adds marker files to each folder that has been
compiled, containing the version of the ngcc used.
When compiling, it will ignore folders that contain these
marker files, as long as the version matches.

As part of the tests run in the CircleCI `aio_monitoring` job, we need
to retrieve `sitemap.xml` from the site under test. Previously, the URL
used to retrieve that contained a double-slash (`//`). At some point,
Firebase (which is used for hosting the site) stopped normalizing
double-slashes to a single slash, causing the test to fail.
This commit fixes the problem by ensuring that the constructed URLs do
not contain double-slashes.

defineComponent() and friends can return a flyweight EMPTY object for
specific fields when they contain no data. InheritDefinitionFeature
was attempting to write into these flyweight objects, which have been
protected with Object.freeze().
This commit adds detection to InheritDefinitionFeature to identify the
frozen objects.

Now that the doc-gen parses the imports of TS source
files we need to ensure that the root node_modules
exists. Otherwise running `yarn docs` produces an
obscure error:
```
Error: No SourceFile found with path node_modules/@types/jasmine/index.d.ts
```
Closes#25759

While creating FESM files, rollup usually drops all unused symbols.
All *__POST_NGCC__ are unused unless ngcc rewires stuff. To prevent this DCE
we reexport them as private symbols. If ngcc is not used, these symbols will
be dropped when we optimize an application bundle.
We don't have an infrastructure to test this fix, so I just manually inspected
the bundles before and after to verify that the fix works.

Closure compiler requires that the i18n message constants of the form
const MSG_XYZ = goog.getMessage('...');
have names that are unique across an entire compilation, even if the
variables themselves are local to a given module. This means that in
practice these names must be unique in a codebase.
The best way to guarantee this requirement is met is to encode the
relative file name of the file into which the constant is being written
into the constant name itself. This commit implements that solution.

TypeScript has a more modern diagnostic emit function which produces
contextually annotated error information, using colors in the console
to indicate where in the code the error occurs.
This commit swiches ngtsc to use this format for diagnostics when
emitting them after a failed compilation.
PR Close#25647
This commit takes the first steps towards ngtsc producing real
TypeScript diagnostics instead of simply throwing errors when
encountering incorrect code.
A new class is introduced, FatalDiagnosticError, which can be thrown by
handlers whenever a condition in the code is encountered which by
necessity prevents the class from being compiled. This error type is
convertable to a ts.Diagnostic which represents the type and source of
the error.
Error codes are introduced for Angular errors, and are prefixed with -99
(so error code 1001 becomes -991001) to distinguish them from other TS
errors.
A function is provided which will read TS diagnostic output and convert
the TS errors to NG errors if they match this negative error code
format.

Previously, benchpress would use `console.time()` and
`console.timeEnd()` to measure the start and end of a test in the
performance log. This used to work over navigations - if you called
`console.time(id)` then navigated to a different page, calling
`console.timeEnd(id)` would still insert an event in the performance
log.
As of Chrome 65, this is no longer the case. `console.timeEnd(id)` will
simply not insert an event in the performance log unless
`console.time(id)` was called on the same page. Likewise, using
`performance.measure()` does not work if the starting mark was on a
different page.
This simple workaround uses `performance.mark()` to insert events in the
performance log at the start and end of the test. Benchpress looks for
'-bpstart' and '-bpend' in the name of the performance mark, and
normalizes that to the start and end events expected by PerflogMetric

When using ViewEncapsulation.ShadowDom, Angular will not remove the child nodes of the DOM node a root Component is bootstrapped into. This enables developers building Angular Elements to use the `<slot>` element to do native content projection.
