Alex Rickabaugh 7983f0a69b ci(ivy): configure CI environments for Ivy JIT and AOT (#24309)
Two new CircleCI environments are created: test_ivy_jit and test_ivy_aot.
Both run a subset of the tests that have been marked with Bazel tags as
being appropriate for that environment.

Once all the tests pass, builds are published to the *-builds repo both
for the legacy View Engine compiled code as well as for ivy-jit and ivy-aot.

Pawel Kozlowski 90bf5d8961 feat(ivy): separate attributes for directive matching purposes (#23991)
In ngIvy directives matching (determining which directives are active based
on a CSS seletor) happens at runtime. This means that runtime needs to have
enough context to match directives. This PR takes care of cases where a directive's
selector should match bindings (ex. [foo]="exp") and event handlers (ex. (out)="do()").
In the mentioned cases we need to have binding / output "attributes" for directive's
CSS selector matching purposes. At the same time those are not regular attributes and
as such should not  be reflected in the DOM.

Alex Rickabaugh 1eafd04eb3 build(ivy): support alternate compilation modes to enable Ivy testing (#24056)
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.

Victor Berchet 4f36340de7 feat(ivy): add support for short-circuiting (#24039)
Short-circuitable expressions (using ternary & binary operators) could not use
the regular binding mechanism as it relies on the bindings being checked every
single time - the index is incremented as part of checking the bindings.

Then for pure function kind of bindings we use a different mechanism with a
fixed index. As such short circuiting a binding check does not mess with the
expected binding index.

Note that all pure function bindings are handled the same wether or not they
actually are short-circuitable. This allows to keep the compiler and compiled
code simple - and there is no runtime perf cost anyway.

Alex Rickabaugh 919f42fea1 feat(ivy): first steps towards JIT compilation (#23833)
This commit adds a mechanism by which the @angular/core annotations
for @Component, @Injectable, and @NgModule become decorators which,
when executed at runtime, trigger just-in-time compilation of their
associated types. The activation of these decorators is configured
by the ivy_switch mechanism, ensuring that the Ivy JIT engine does
not get included in Angular bundles unless specifically requested.

Miško Hevery 3fb4e190a8 fix(ivy): correctly bind to component context (#23168)
When compiling templates the compiler would often bind to
closest context rather than the component context.

The only time one should be binding to the cont component is
in explicit cases where the inner template declares local variable.

Pawel Kozlowski d80e9304c6 fix(ivy): properly find RNode (#23193)
As we no longer create native (RNode) comment nodes for containers,
we need to execute logic for finding a next sibiling node with RNode
when inserting a view.

The mentioned logic need to be updated for the case of dynamically
created containers (LContainerNode). Indeed, we need to be able to
descend into dynamically inserted views while looking for a RNode.
To achieve this we need to have a pointer from a host LNode to a
dynamically created LContainerNode).

Please note that the 'archive' option still doesn't
work correctly as listening to component outputs doesn't
seem to work (onArchive() is never called).

Alex Rickabaugh fab6b39c3d fix(core): inject() should always work in an NgModule injection scope (#23148)
Currently the context for inject() is only set when the token is seen
for the first time. This has two issues:

* It should always be set when injecting from that injector, because
  a constructor may wish to call inject() directly.
* If an NgModuleFactory is .create()'d twice, and an ngInjectableDef
  token is requested from each of them, the second time will fail.
  This is because the first injection adds the provider definition
  and calls the factory, and the provider definitions are shared.
  The second injector will see the provider definition and call the
  factory to create an instance, but without setting the correct
  context for inject().

Fixes angular/material2#10586.
