In the ReflectionHost API, a 'viaModule' indicates that a particular value
originated in another absolute module. It should always be 'null' for values
originating in relatively-imported modules.
This commit fixes a bug in the CommonJsReflectionHost where viaModule would
be reported even for relatively-imported values, which causes invalid import
statements to be generated during compilation.
A test is added to verify the correct behavior.

This allows disabling parallelism in ngcc if desired, which is mainly useful
for debugging. The implementation creates the flag and passes its value to
mainNgcc.
No tests are added since the feature mainly exists already - ngcc supports
both parallel and serial execution. This commit only allows switching the
flag via the commandline.

Prior to this commit, the absolute spans (relative to template source
file rather than the start of an expression) of expressions in a
template attribute like `*ngIf` were generated incorrectly, equating to
the relative spans.
This fixes the bug by passing an `absoluteOffset` parameter when parsing
template bindings.
Through some levels of indirection, this is required for the Language
Service to support text replacement in

Prior to this fix if a map-based class or style binding wrote
its values onto an elemenent, the internal styling context would
not register the binding if the initial value as a `NO_CHANGE`
value. This situation occurs if a directive takes control of the
`class` or `style` input values and then returns a `NO_CHANGE` value
if the initial value is empty.
This patch ensures that all bindings are always registered with the
`TStylingContext` data-structure even if their initial value is
an instance of `NO_CHANGE`.

Prior to this fix, all style/class bindings (e.g. `[style]` and
`[class.foo]`) would quietly update a binding value if and when the
current binding value changes during checkNoChanges.
With this patch, all styling instructions will properly check to see
if the value has changed during the second pass of detectChanges()
if checkNoChanges is active.

Previously, when `ngcc` was reflecting on class members it did not
account for the fact that a member could be of the kind
`IndexSignature`. This can happen, for example, on abstract classes (as
is the case for [JsonCallbackContext][1]).
Trying to reflect on such members (and failing to recognize their kind),
resulted in warnings, such as:
```
Warning: Unknown member type: "[key: string]: (data: any) => void;
```
While these warnings are harmless, they can be confusing and worrisome
for users.
This commit avoids such warnings by detecting class members of the
`IndexSignature` kind and ignoring them.

Turns out that writing to global state is more expensive than writing to
a property on an object.
Slower:
````
let count = 0;
function increment() {
count++;
}
```
Faster:
````
const state = {
count: 0
};
function increment() {
state.count++;
}
```
This change moves all of the instruction state into a single state object.

Prior to this commit, all `className` inputs were not set because the runtime code assumed that the `classMap` instruction is only generated for `[class]` bindings. However the `[className]` binding also produces the same `classMap`, thus the code needs to distinguish between `class` and `className`. This commit adds extra logic to select the right input name and also throws an error in case `[class]` and `[className]` bindings are used on the same element simultaneously.

Prior to this change, the template type checker would incorrectly bind
non-property bindings such as `[class.strong]`, `[style.color]` and
`[attr.enabled]` to directive inputs of the same name. This is
undesirable, as those bindings are never actually bound to the inputs at
runtime.

This commit speeds up the tests by calling `MockHost.reset()` in

This change assures that data structures related to initial inputs
(ones set from static attributes) are created only once (during the
first template pass) and no additional runtime checks are done for
subsequent passes.
Additionally this commit changes the data structure used by initial inputs
on TNode - previously initial inputs for a directive were stored at the
directive index in LView. This meant that an array holding initial inputs
was relativelly big and had many null elements (as placeholders for elements,
directives, injector etc.). After the change we only create an array of a size
equal to a number of directives matched on a given TNode.
For the `directive_instantiate` benchmark it boils to allocating a 1-element
array vs. 100-element array previously.

Now, hovering over an attribute on an element will provide information
about the directive that attribute matches in the element, if any.
(More generally, we return information about directive symbols
matched on an element attribute.)
I believe this is similar to how the indexer provides this kind of
information, though more precise in the sense that this commit provides
directive information only if the directive selector exactly matches the
attribute selector. In another sense, this is a limitation.
In fact, there are the limitations of:
- Directives matched on the element, but with a selector of anything
more than the attribute (e.g. `div[string-model]` or
`[string-model][other-attr]`) will not be returned as symbols matching
on the attribute.
- Only one symbol can be returned currently. If the attribute matches
multiple directives, only one directive symbol will be returned.
Furthermore, we cannot say that the directive symbol returned is
determinstic.
Resolution of these limitations can be discussed in the future. At least
the second limitation should be very easy to fixup in a future commit.
This relies solely on the template compiler and is agnostic to any Ivy
changes, so this is strictly a feature enhancement that will not have to
be refactored when we migrate the language service to Ivy.

Prior to this change, a static attribute that corresponds with a
directive's input would not be type-checked against the type of the
input. This is unfortunate, as a static value always has type `string`,
whereas the directive's input type might be something different. This
typically occurs when a developer forgets to enclose the attribute name
in brackets to make it a property binding.
This commit lets static attributes be considered as bindings with string
values, so that they will be properly type-checked.

This commit introduces an internal config option of the template type
checker that allows to disable strict null checks of input bindings to
directives. This may be particularly useful when a directive is from a
library that is not compiled with `strictNullChecks` enabled.
Right now, strict null checks are enabled when `fullTemplateTypeCheck`
is turned on, and disabled when it's off. In the near future, several of
the internal configuration options will be added as public Angular
compiler options so that users can have fine-grained control over which
areas of the template type checker to enable, allowing for a more
incremental migration strategy.
