The `TNode.cleanup` data structure can contain sequences of 4-element
sequence of entries (event handlers, directive outputs) mixed with
2-element sequence of entries (QueryList cleanup). Before this fix
we would always skip 4 elements in the `TNode.cleanup` while looking
up event handler cleanups. 4-element skips are not correct in case
of query cleanup presence and this commit corrects the algorithm to
jump 4 or 2 elements depending on a type of cleanup encountered.

If a component has its definition set by defineComponent (as opposed to
JIT getter), then it will generate a factory that uses directiveInject()
to retrieve its dependencies. This can be problematic in test code because
tests could use the injection utility before bootstrapping the component,
and directiveInject() relies on the view having been created.
This commit tweaks directiveInject() to fall back to inject() if the view
has not been created. This will allow injection to work in tests even if
it is called before the component is bootstrapped.

Previous to this commit, providing a component or directive in a test
module without @Injectable() would throw because the injectable factory
would not be found. Providing components in tests in addition to declaring
or importing them is not necessary, but it should not throw an error.
This commit ensures factory data is saved when component defs and directive
defs are created, which allows them to be processed by the module injector.
Note that bootstrapping is still required for this setup to work because
directiveInject() does not support cases where the view has not been
created. This case will be handled in a future commit.

We had a bug where event.preventDefault() was not always called if listeners
were coalesced. This is because we were overwriting the previous listener's
result every time we called the next listener, so listeners early in the chain
that returned false would be ignored and preventDefault would not be called.
This commit fixes that issue, so now preventDefault() is called if any listener
in a coalesced chain returns false. This brings us in line with View Engine
behavior.

Because the styling context may be stored in a different location
and be apart of a sub array, reading the styling context each time
a host binding is evaluated is costly. This patch ensures that the
active styling context is cached so that multiple interactions with
styling bindings can easily retrieve the styling context efficiently.

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

Previously, this check was done with bracket property access on the
global object: global['goog']
This will not be minified when Closure compiles this code, which:
1) breaks, because 'goog' will have been minified but the check won't have
taken that into consideration
2) causes build failures in g3, because the actual property 'goog' is
forbidden in some published JS code (to ensure obfuscation).
A TODO is added to validate that this logic is correct, as it's difficult to
test within the Angular repo.

So far using runtime i18n with ivy meant that you needed to use Closure and `goog.getMsg` (or a polyfill). This PR changes the compiler to output both closure & non-closure code, while the unused option will be tree-shaken by minifiers.
This means that if you use the Angular CLI with ivy and load a translations file, you can use i18n and the application will not throw at runtime.
For now it will not translate your application, but at least you can try ivy without having to remove all of your i18n code and configuration.

Currently in Ivy we pass both the raw and parsed selectors to the projectionDef instruction, because the parsed selectors are used to match most nodes, whereas the raw ones are used to match against nodes with the ngProjectAs attribute. The raw selectors add a fair bit of code that won't be used in most cases, because ngProjectAs is somewhat rare.
These changes rework the compiler not to output the raw selectors in the projectionDef, but to parse the selector in ngProjectAs and to store it on the TAttributes. The logic for matching has also been changed so that it matches the pre-parsed ngProjectAs selector against the list of projection selectors.

While investigating styling performance regressions, it was discovered
that a single `fn(...args)` operation was causing a performance hit
because the generated es5 `__spread` operation uses `[].concat` and
reads from the `arguments` values (which are not very efficient). This
patch changes that around to use `fn.apply` instead.

In order to optimize performance for styling-related operations in
Angular, debug counters need to be introduced. This patch adds various
counters to ngDevMode which are fired each time a styling-related
binding is updated.

The new styling algorithm in angular is designed to evaluate host
bindings stylinh priority in order of directive evaluation order. This,
however, does not work with respect to parent/sub-class directives
because sub-class host bindings are run after the parent host bindings
but still have priority. This patch ensures that the host styling bindings
for parent and sub-class components/directives are executed with respect
to the styling algorithm prioritization.

This new interface will match classes whether they are abstract or

Type isn't used yet so this isn't a breaking change.

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.
