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.

The optional property on `ts.CompilerHost` is called `realpath` (lower
case), not `realPath` (lower camel case).
It is not clear to me what the impact of this is, but the author's
intent was clearly to override `realpath`.

ngtsc used to have a custom ts.CompilerHost which delegated to the plain
ts.CompilerHost. There's no need for this wrapper class and it causes
issues with CLI integration, so delete it.

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.
PR Close#24572
Bazel has a restriction that a single output (eg. a compiled version of
//packages/common) can only be produced by a single rule. This precludes
the Angular repo from having multiple rules that build the same code. And
the complexity of having a single rule produce multiple outputs (eg. an
ngc-compiled version of //packages/common and an Ivy-enabled version) is
too high.
Additionally, the Angular repo has lots of existing tests which could be
executed as-is under Ivy. Such testing is very valuable, and it would be
nice to share not only the code, but the dependency graph / build config
as well.
Thus, this change introduces a --define flag 'compile' with three potential
values. When --define=compile=X is set, the entire build system runs in a
particular mode - the behavior of all existing targets is controlled by
the flag. This allows us to reuse our entire build structure for testing
in a variety of different manners. The flag has three possible settings:
* legacy (the default): the traditional View Engine (ngc) build
* local: runs the prototype ngtsc compiler, which does not rely on global
analysis
* jit: runs ngtsc in a mode which executes tsickle, but excludes the
Angular related transforms, which approximates the behavior of plain
tsc. This allows the main packages such as common to be tested with
the JIT compiler.
Additionally, the ivy_ng_module() rule still exists and runs ngc in a mode
where Ivy-compiled output is produced from global analysis information, as
a stopgap while ngtsc is being developed.
PR Close#24056
This commit adds a new compiler pipeline that isn't dependent on global
analysis, referred to as 'ngtsc'. This new compiler is accessed by
running ngc with "enableIvy" set to "ngtsc". It reuses the same initialization
logic but creates a new implementation of Program which does not perform the
global-level analysis that AngularCompilerProgram does. It will be the
foundation for the production Ivy compiler.

The compiler host would force any file that is in node_modules
into the list of files that needed to be type checked which
captures .js files if `allowJs` is set to `true`. This should
have only forced .d.ts files into the project to enable
generation of factories.
Fixes: #19757
- update to TypeScript 2.5
- point the 2.4 typings test at the previous typescript version, so we
don't break it accidentally
- widen the peerDeps from Angular packages that depend on TypeScript
- update to latest TypeScript 2.5 compatible Bazel rules
- move .bazelrc to tools/bazel.rc per https://docs.bazel.build/versions/master/best-practices.html#bazelrc

This change is needed to prevent users’ builds from breaking.
If a user sets `fullTemlateTypeCheck` to true, we will
continue to check the templates even when `skipTemplateCodegen` is true
as well.

If no user files changed:
- only type check the changed generated files
Never emit non changed generated files
- we still calculate them, but don’t send them through
TypeScript to emit them but cache the written files instead.

This is important to not confuse users nor downstream tools that
consume our source maps. For generated content for which we don’t
have an original source file, we use the generated file now.

For now, we always create all generated files, but diff them
before we pass them to TypeScript.
For the user files, we compare the programs and only emit changed
TypeScript files.
This also adds more diagnostic messages if the `—diagnostics` flag
is passed to the command line.

We now create 2 programs with exactly the same fileNames and
exactly the same `import` / `export` declarations,
allowing TS to reuse the structure of first program
completely. When passing in an oldProgram and the files didn’t change,
TS can also reuse the old program completely.
This is possible buy adding generated files to TS
in `host.geSourceFile` via `ts.SourceFile.referencedFiles`.
This commit also:
- has a minor side effect on how we generate shared stylesheets:
- previously every import in a stylesheet would generate a new
`.ngstyles.ts` file.
- now, we only generate 1 `.ngstyles.ts` file per entry in `@Component.styleUrls`.
This was required as we need to be able to determine the program files
without loading the resources (which can be async).
- makes all angular related methods in `CompilerHost`
optional, allowing to just use a regular `ts.CompilerHost` as `CompilerHost`.
- simplifies the logic around `Compiler.analyzeNgModules` by introducing `NgAnalyzedFile`.

This is a corner case, and converting them is what
was expected in G3. This also fits the fact that
we already convert package paths into relative paths.

Windows paths have back slashes, but TypeScript expects to always have forward slashes.
In other places where this call happens (like `src/compiler_host.ts`) the same fix is present.
