JoostK 60afe88bcc feat(ivy): do not emit empty providers/imports for defineInjector (#29598)
The defineInjector function specifies its providers and imports array to
be optional, so if no providers/imports are present these keys may be
omitted. This commit updates the compiler to only generate the keys when
necessary.

JoostK 2d372f48db feat(ivy): exclude declarations from injector imports (#29598)
Prior to this change, a module's imports and exports would be used verbatim
as an injectors' imports. This is detrimental for tree-shaking, as a
module's exports could reference declarations that would then prevent such
declarations from being eligible for tree-shaking.

Since an injector actually only needs NgModule references as its imports,
we may safely filter out any declarations from the list of module exports.
This makes them eligible for tree-shaking once again.

JoostK 45c6360e5a feat(ivy): emit module scope metadata using pure function call (#29598)
Prior to this change, all module metadata would be included in the
`defineNgModule` call that is set as the `ngModuleDef` field of module
types. Part of the metadata is scope information like declarations,
imports and exports that is used for computing the transitive module
scope in JIT environments, preventing those references from being
tree-shaken for production builds.

This change moves the metadata for scope computations to a pure function
call that patches the scope references onto the module type. Because the
function is marked pure, it may be tree-shaken out during production builds
such that references to declarations and exports are dropped, which in turn
allows for tree-shaken any declaration that is not otherwise referenced.

Pete Bacon Darwin 6b39c9cf32 fix(compiler-cli): ngcc - cope with processing entry-points multiple times (#29657)
With the new API, where you can choose to only process the first
matching format, it is possible to process an entry-point multiple
times, if you pass in a different format each time.

Previously, ngcc would always try to process the typings files for
the entry-point along with processing the first format of the current
execution of ngcc. But this meant that it would be trying to process
the typings a second time.

Now we only process the typings if they have not already been
processed as part of processing another format in another
even if it was in a different execution of ngcc.

JoostK 98f8b0f328 fix(ivy): ngcc - properly handle aliases class expressions (#29119)
In ES2015, classes could have been emitted as a variable declaration
initialized with a class expression. In certain situations, an intermediary
variable suffixed with `_1` is present such that the variable
declaration's initializer becomes a binary expression with its rhs being
the class expression, and its lhs being the identifier of the intermediate
variable. This structure was not recognized, resulting in such classes not
being considered as a class in `Esm2015ReflectionHost`.

As a consequence, the analysis of functions/methods that return a
`ModuleWithProviders` object did not take the methods of such classes into
account.

Another edge-case with such intermediate variable was that static
properties would not be considered as class members. A testcase was added
to prevent regressions.

Pete Bacon Darwin 9f54d76ef5 refactor(upgrade): use Bazel packages to avoid symlinks in the source (#29466)
Previously we had to share code between upgrade/dynamic and upgrade/static
by symlinking the `src` folder, which allowed both packages to access
the upgrade/common files.

These symlinks are always problematic on Windows, where we had to run
a script to re-link them, and restore them.

This change uses Bazel packages to share the `upgrade/common` code,
which avoids the need for symlinking the `src` folder.

Also, the Windows specific scripts that fixup the symlinks have also
been removed as there is no more need for them.

George Kalpakas 0e201ea9d8 fix(docs-infra): fix scroll position restoration error in `ScrollService` (#29658)
Based on Google Analytics error report, the following error happens
occasionally (15% or total errors for 2019-03):

```
Cannot read property '0' of null TypeError: at t.scrollToPosition@main.js
```

This was a result of calling [ViewportScroller#scrollToPosition()][1]
with `null`, which in turn happens when calling
[ScrollService#scrollToPosition()][2] while `this.scrollPosition` is
`null`. This can be a result of a `popstate` event without an associated
history state.

This commit fixes the error by checking whether `this.scrollPosition` is
`null`, before using it with `scrollToPosition()`.

(It also refactors away the unneeded internal `popStateFired` property.)

Alex Rickabaugh 7041e61562 perf(ivy): basic incremental compilation for ngtsc (#29380)
This commit introduces a mechanism for incremental compilation to the ngtsc
compiler.

Previously, incremental information was used in the construction of the
ts.Program for subsequent compilations, but was not used in ngtsc itself.

This commit adds an IncrementalState class, which tracks state between ngtsc
compilations. Currently, this supports skipping the TypeScript emit step
when the compiler can prove the contents of emit have not changed.

This is implemented for @Injectables as well as for files which don't
contain any Angular decorated types. These are the only files which can be
proven to be safe today.

See ngtsc/incremental/README.md for more details.

Alex Rickabaugh 7316212c1e test(ivy): support multiple compilations in the ngtsc test env (#29380)
This commit adds support for compiling the same program repeatedly in a way
that's similar to how incremental builds work in a tool such as the CLI.

* support is added to the compiler entrypoint for reuse of the Program
  object between compilations. This is the basis of the compiler's
  incremental compilation model.

* support is added to wrap the CompilerHost the compiler creates and cache
  ts.SourceFiles in between compilations.

* support is added to track when files are emitted, for assertion purposes.

* an 'exclude' section is added to the base tsconfig to prevent .d.ts
  outputs from the first compilation from becoming inputs to any subsequent
  compilations.

Alex Rickabaugh 3e569767e3 fix(ivy): avoid remote scoping if it's not actually required (#29404)
Currently, ngtsc decides to use remote scoping if the compilation of a
component may create a cyclic import. This happens if there are two
components in a scope (say, A and B) and A directly uses B. During
compilation of B ngtsc will then note that if B were to use A, a cycle would
be generated, and so it will opt to use remote scoping for B.

ngtsc already uses the R3TargetBinder to correctly track the imports that
are actually required, for future cycle tracking. This commit expands that
usage to not trigger remote scoping unless B actually does consume A in its
template.

Jason Aden f9497bf28b fix(router): adjust setting navigationTransition when a new navigation cancels an existing one (#29636)
Prior to this change, if a navigation was ongoing and a new one came in, the router could get into a state where `router.currentNavigation` was `null` even though a navigation was executing. This change moves where we set the `currentNavigation` value so it's inside a `switchMap`. This solves the problem because the `finally` on the `switchMap` had been setting `currentNavigation` to `null` but the new `currentNavigation` value would have already been set. Essentially this was a timing problem and is resolved with this change.
