Prior to this commit, the unknown element can happen twice for AOT-compiled components: once during compilation and once again at runtime. Due to the fact that `schemas` information is not present on Component and NgModule defs after AOT compilation, the second check (at runtime) may fail, even though the same check was successful at compile time. This commit updates the code to avoid the second check for AOT-compiled components by checking whether `schemas` information is present in a logic that executes the unknown element check.

When creating synthesized tagged template literals, one must provide both
the "cooked" text and the "raw" (unparsed) text. Previously there were no
good APIs for creating the AST nodes with raw text for such literals.
Recently the APIs were improved to support this, and they do an extra
check to ensure that the raw text parses to be equal to the cooked text.
It turns out there is a bug in this check -
see https://github.com/microsoft/TypeScript/issues/35374.
This commit works around the bug by synthesizing a "head" node and morphing
it by changing its `kind` into the required node type.

With Angular CLI version 9 RC 3 we can run a single migration for a package using the name of the migration schematic.
We need to pass the schematic name as a value to the `migrate-only` option.

This bring is changes to the @nodejs repository required for https://github.com/angular/angular/pull/33927. See release notes for more details: https://github.com/bazelbuild/rules_nodejs/releases/tag/0.41.0.
rules_nodejs is approaching 1.0 and breaking changes for that release are being made more frequently. In this release, the ts_devserver API changed and it no longer injects html script tags into a provided index.html file. The diff on this commit is large as this breaking change affects quite a few tests.
Also note that we don’t update @angular/bazel schematics and integration/bazel as 0.41.0 is not a recommended update for angular users yet due to the breaking changes in ts_devserver & web_package (now named pkg_web). When a suitable plain npm package that is in progress is finished then it will be possible to easily replace the html injection functionality removed from ts_devserver & pkg_web.

Commit 53fc2ed8bf added support for
determining index types accessed using index signatures, but did not
include support for index types accessed using dot notation:
```typescript
const obj<T>: { [key: string]: T };
obj['stringKey']. // gets `T.` completions
obj.stringKey. // did not peviously get `T.` completions
```
This adds support for determining an index type accessed via dot
notation by rigging an object's symbol table to return the string index
signature type a property access refers to, if that property does not
explicitly exist on the object. This is very similar to @ivanwonder's
work in #29811.
`SymbolWrapper` now takes an additional parameter to explicitly set the
type of the symbol wrapped. This is done because
`SymbolTableWrapper#get` only has access to the symbol of the index
type, _not_ the index signature symbol itself. An attempt to get the
type of the index type will give an error.

Prior to this commit, there was a runtime check in i18n logic to make sure "other" case is always present in an ICU. That was not a requirement in View Engine, so ICUs that previously worked may produce errors. This commit removes that restriction and adds support for ICUs without "other" cases.

When inserting a `viewRef` it is possible to not provide
an `index`, which is regarded as appending to the end of
the container.
If the `viewRef` already exists in the container, then
this results in a move. But there was a fault in the logic
that computed where to insert the `viewRef` that did not
account for the fact that the `viewRef` was already in
the container, so the insertion `index` was outside the
bounds of the array.

This commit fixes a compatibility bug where pre-order lifecycle
hooks (onInit, doCheck, OnChanges) for directives on the same
host node were executed based on the order the directives were
matched, rather than the order the directives were instantiated
(i.e. injection order).
This discrepancy can cause issues with forms, where it is common
to inject NgControl and try to extract its control property in
ngOnInit. As the NgControl directive is injected, it should be
instantiated before the control value accessor directive (and
thus its hooks should run first). This ensures that the NgControl
ngOnInit can set up the form control before the ngOnInit
for the control value accessor tries to access it.

In ViewEngine we were only generating code for exported classes, however with Ivy we do it no matter whether the class has been exported or not. These changes add an extra flag that allows consumers to opt into the ViewEngine behavior. The flag works by treating non-exported classes as if they're set to `jit: true`.

Previously, our incremental build system kept track of the changes between
the current compilation and the previous one, and used its knowledge of
inter-file dependencies to evaluate the impact of each change and emit the
right set of output files.
However, a problem arose if the compiler was not able to extract a
dependency graph successfully. This typically happens if the input program
contains errors. In this case the Angular analysis part of compilation is
never executed.
If a file changed in one of these failed builds, in the next build it
appears unchanged. This means that the compiler "forgets" to emit it!
To fix this problem, the compiler needs to know the set of changes made
_since the last successful build_, not simply since the last invocation.
This commit changes the incremental state system to much more explicitly
pass information from the previous to the next compilation, and in the
process to keep track of changes across multiple failed builds, until the
program can be analyzed successfully and the results of those changes
incorporated into the emit plan.

Due to the fact that Tsickle runs between analyze and transform phases in Angular, Tsickle may transform nodes (add comments with type annotations for Closure) that we captured during the analyze phase. As a result, some patterns where a function is returned from another function may trigger automatic semicolon insertion, which breaks the code (makes functions return `undefined` instead of a function). In order to avoid the problem, this commit updates the code to wrap all functions in some expression ("privders" and "viewProviders") in parentheses.

When ngtsc comes across a source file during partial evaluation, it
would determine all exported symbols from that module and evaluate their
values greedily. This greedy evaluation strategy introduces unnecessary
work and can fall into infinite recursion when the evaluation result of
an exported expression would circularly depend on the source file. This
would primarily occur in CommonJS code, where the `exports` variable can
be used to refer to an exported variable. This variable would be
resolved to the source file itself, thereby greedily evaluating all
exported symbols and thus ending up evaluating the `exports` variable
again. This variable would be resolved to the source file itself,
thereby greedily evaluating all exported symbols and thus ending u
evaluating the `exports` variable again. This variable would be
resolved to the source file itself, thereby greedily evaluating all
exported symbols and thus ending up evaluating the `exports` variable
again. This variable would be resolved to the source file itself,

until all stack frames were exhausted.
This commit introduces a `ResolvedModule` that delays the evaluation of
its exports until they are actually requested. This avoids the circular
dependency when evaluating `exports`, thereby fixing the issue.
