For Ivy's template type checker it is possible to let a directive
specify static members to allow a wider type for some input:
```typescript
export class MatSelect {
@Input() disabled: boolean;
static ngAcceptInputType_disabled: boolean | string;
}
```
This allows a binding to the `MatSelect.disabled` input to be of type
boolean or string, whereas the `disabled` property itself is only of
type boolean.
Up until now, any static `ngAcceptInputType_*` property was not
inherited for subclasses of a directive class. This is cumbersome, as
the directive's inputs are inherited, so any acceptance member should as
well. To resolve this limitation, this commit extends the flattening of
directive metadata to include the acceptance members.

TypeScript 3.7 flags `if` conditions that implicitly coerce a function/method definition. While checking for the `template` presence on a def (actually checking whether we work with Component) in `saveNameToExportMap`, the `if` condition had implicit type coercion. This commit updates the condition to use the `isComponentDef` function (that checks `def.template` against `null` internally) to avoid compilation errors with TypeScript 3.7.

Prior to this commit, values wrapped into SafeStyle were not handled correctly in [style.prop] bindings in case style sanitizer is present (when template contains some style props that require sanitization). Style sanitizer was not unwrapping values in case a given prop doesn't require sanitization.As a result, wrapped values were used as final styling values (see https://github.com/angular/angular/blob/master/packages/core/src/render3/styling/bindings.ts#L620). This commit updates the logic to unwrap safe values in sanitizer in case no sanitization is required.

The undecorated child migration creates a synthetic decorator, which
contained `"exportAs": ["exportName"]` as obtained from the metadata of
the parent class. This is a problem, as `exportAs` needs to specified
as a comma-separated string instead of an array. This commit fixes the
bug by transforming the array of export names back to a comma-separated
string.

When ngcc is analyzing synthetically inserted decorators from a
migration, it is typically not expected that any diagnostics are
produced. In the situation where a diagnostic is produced, however, the
diagnostic would not be reported at all. This commit ensures that
diagnostics in migrations are reported.

The compiler exports a `formatDiagnostics` function which consumers can use
to print both ts and ng diagnostics. However, this function was previously
using the "old" style TypeScript diagnostics, as opposed to the modern
diagnostic printer which uses terminal colors and prints additional context
information.
This commit updates `formatDiagnostics` to use the modern formatter, plus to
update Ivy's negative error codes to Angular 'NG' errors.
The Angular CLI needs a little more work to use this function for printing
TS diagnostics, but this commit alone should fix Bazel builds as ngc-wrapped
goes through `formatDiagnostics`.

In Ivy, if you do:
`TestBed.configureTestingModule({providers: [{provide: Service}]});`
the injector will attempt to inject Service as if it was simply listed
in the providers array like `{providers: [Service]}`
This fixes an inconsistency when similarly providing an override with no
`useValue` or `useFactory`.

Previously, ternary expressions were emitted as:
condExpr ? trueCase : falseCase
However, this causes problems when ternary operations are nested. In
particular, a template expression of the form:
a?.b ? c : d
would have compiled to:
a == null ? null : a.b ? c : d
The ternary operator is right-associative, so that expression is interpreted
as:
a == null ? null : (a.b ? c : d)
when in reality left-associativity is desired in this particular instance:
(a == null ? null : a.b) ? c : d
This commit adds a check in the expression translator to detect such
left-associative usages of ternaries and to enforce such associativity with
parentheses when necessary.
A test is also added for the template type-checking expression translator,
to ensure it correctly produces right-associative expressions for ternaries
in the user's template.

Remove the remaining check for compile build variable in the ng_module
rule. Now that components is no longer relying on this build variable
we can safely remove it from our repository.
We will leave the remaining check for if the compile build variable is
used within our own repo, with plans to remove it in a couple months.
It is being kept in place to ensure that uncommitted local scripts for
our own development that we have locally, kill error as expected if
they still reference the compile build variable.

Also supports optionally setting a namespace which will be added to the name automatically (e.g. `foo` will be renamed to `ng.foo`). Relevant APIs should also be exported through the `global.ts` file which will show up under `core/global`.

Due to a bug in the existing banner, `typescript` module was require-d
instead of reusing the module passed in from tsserver.
This bug is caused by some source files in language-service that imports
`typescript` instead of `typescript/lib/tsserverlibrary`.
This is not an unsupported use case, it's just that when typescript is
resolved in the banner we have to be very careful about which modules to
"require".
The convoluted logic in the banner makes it very hard to detect
anomalies. This commit cleans it up and removes a lot of unneeded code.
This commit also removes `ts` import in typescript_host.ts and use `tss`
instead to make it less confusing.

Currently all saucelabs usage in our repos is done using the same
account angular-ci. By migrating to use individual accounts
for each repo, we can better track the usage for each repo as well
as providing concurrency limiting on a per repo basis.
Additionally, we no longer use two separate accounts based on being

Previously the `rootDir` was set to the entry-point path but
this is incorrect if the source files are stored in a directory outside
the entry-point path. This is the case in the latest versions of the
Angular CDK.
Instead the `rootDir` should be the containing package path, which is
guaranteed to include all the source for the entry-point.
---
A symptom of this is an error when ngcc is trying to process the source of
an entry-point format after the entry-point's typings have already been
processed by a previous processing run.
During processing the `_toR3Reference()` function gets called which in turn
makes a call to `ReflectionHost.getDtsDeclaration()`. If the typings files
are also being processed this returns the node from the dts typings files.
But if we have already processed the typings files and are now processing
only an entry-point format without typings, the call to
`ReflectionHost.getDtsDeclaration()` returns `null`.
When this value is `null`, a JS `valueRef` is passed through as the DTS
`typeRef` to the `ReferenceEmitter`. In this case, the `ReferenceEmitter`
fails during `emit()` because no `ReferenceEmitStrategy` is able to provide
an emission:
1) The `LocalIdentifierStrategy` is not able help because in this case
`ImportMode` is `ForceNewImport`.
2) The `LogicalProjectStrategy` cannot find the JS file below the `rootDir`.
The second strategy failure is fixed by this PR.
