If the testcase has not specified that errors were expected, then any
errors that have occurred should be reported. These errors may have
prevented an output file from being generated, which resulted in hard

In the new behavior Angular removes applications from the testability registry when the
root view gets destroyed. This eliminates a memory leak, because before that the
TestabilityRegistry holds references to HTML elements, thus they cannot be GCed.

The Language Service "find references" currently uses the
`ngtypecheck.ts` suffix to determine if a file is a shim file. Instead,
a better API would be to expose a method in the template type checker
that does this verification so that the LS does not have to "know" about
the typecheck suffix. This also fixes an issue (albeit unlikely) whereby a file
in the user's program that _actually_ is named with the `ngtypecheck.ts`
suffix would have been interpreted as a shim file.

This commit adds "find references" functionality to the Ivy integrated
language service. The basic approach is as follows:
1. Generate shims for all files to ensure we find references in shims
throughout the entire program
2. Determine if the position for the reference request is within a
template.
* Yes, it is in a template: Find which node in the template AST the
position refers to. Then find the position in the shim file for that
template node. Pass the shim file and position in the shim file along
to step 3.
* No, the request for references was made outside a template: Forward
the file and position to step 3.
3. (`getReferencesAtTypescriptPosition`): Call the native TypeScript LS
`getReferencesAtPosition`. For each reference that is in a shim file, map those
back to a template location, otherwise return it as-is.

There were two issues with the current TCB:
1. The logic for only wrapping the right hand side of the property write
if it was not already a parenthesized expression was incorrect. A
parenthesized expression could still have a trailing comment, and if
that were the case, that span comment would still be ambiguous, as explained
by the comment in the code before `wrapForTypeChecker`.
2. The right hand side of keyed writes was not wrapped in parens at all

In order to map the a safe property read's method access in the type check block
directly back to the property in the template source, we need to
include the `SafePropertyRead`'s `nameSpan` with the `ts.propertyAccess` for
the pipe's transform method.
Note that this is specifically relevant to the Language Service's "find
references" feature. As an example, with something like `{{a?.value}}`,
when calling "find references" on the 'value' we want the text
span of the reference to just be `value` rather than the entire source
`a?.value`.

In order to map the pipe's `transform` method in the type check block
directly back to the pipe name in the template source, we need to
include the `BindingPipe`'s `nameSpan` with the `ts.methodAccess` for

Note that this is specifically relevant to the Language Service's "find
references" feature. As an example, with something like `-2.5 | number:'1.0-0'`,,
when calling "find references" on the 'number' pipe we want the text
span of the reference to just be `number` rather than the entire binding
pipe's source `-2.5 | number:'1.0-0'`.

Fix a case where, if the parent class had already been patched, it would

Currently we convert objects to strings using `'' + value` which is quickest,
but it stringifies the value using its `valueOf`, rather than `toString`. These
changes switch to using `String(value)` which has identical performance
and calls the `toString` method as expected. Note that another option
was calling `toString` directly, but benchmarking showed it to be slower.
I've included the benchmark I used to verify the performance so we have it
for future reference and we can reuse it when making changes to `renderStringify`
in the future.
Also for reference, here are the results of the benchmark:
```
Benchmark: renderStringify
concat: 2.006 ns(0%)
concat with toString: 2.201 ns(-10%)
toString: 237.494 ns(-11741%)
toString with toString: 121.072 ns(-5937%)

We currently only wrap the event listener in the function which ensures
ancestors are marked for check when the listener is placed on an element
that has a native method for listening to an event. We actually need to do
this wrapping in all cases so that events that are attached to non-rendered
template items (`ng-template` and `ng-container`) also mark ancestors for check
when they receive the event.

The ARB format is a JSON file containing an object where the keys are the
message ids and the values are the translations.
It is extensible because it can also contain metadata about each message.
For example:
```
{
"@@locale": "...",
"message-id": "Translated message string",
"@message-id": {
"type": "text",
"description": "Some description text",
"x-locations": [{ "start": {"line": 23, "column": 145}, "file": "some/file.ts" }]
},
}

This commit implements partial compilation of components, together with
linking the partial declaration into its full AOT output.
This commit does not yet enable accurate source maps into external
templates. This requires additional work to account for escape sequences
which is non-trivial. Inline templates that were represented using a
string or template literal are transplated into the partial declaration
output, so their source maps should be accurate. Note, however, that
the accuracy of source maps is not currently verified in tests; this is
also left as future work.
The golden files of partial compilation output have been updated to
reflect the generated code for components. Please note that the current
output should not yet be considered stable.

In production mode this flag defaults to `true`, but the compliance
tests override this to `false` unless it is provided. As such, the
linker should also adhere to this default as otherwise the compilation
output would not align with the output of the full tests.
There are still tests that exercise the value of this flag, together
with it being `undefined` to verify the behavior of the actual default
value.

This commit adds the `i18nUseExternalIds` option to the linker options,
as the compliance tests exercise compilation results with and without
this flag enabled. We therefore need to configure the linker to take
this option into account, as otherwise the compliance test output would
not be identical.
Additionally, this commit switches away from spread syntax to set
the default options. This introduced a problem when the user-provided
options object did specify the keys, but with an undefined value. This
would have prevented the default options from being applied.

The metadata specification of queries allows for the boolean properties
`first`, `descendants` and `static` to be missing, but the linker did

The compilation result of components may have inserted template
functions into the constant pool, which would be inserted into the Babel
AST upon program exit. Babel will then proceed with visiting this newly
inserted subtree, but we have already cleaned up the linker instance
when exiting the program. Any call expressions within the template
functions would then fail to be processed, as a file linker would no
longer be available.
Since the inserted AST subtree is known not to contain yet more partial
declarations, it is safe to skip visiting call expressions when no
file linker is available.

The type checker had to do extensive work in resolving the
`NodePath.get` method call for the `NodePath` that had an intersection
type of `ts.VariableDeclarator&{init:t.Expression}`. The `NodePath.get`
method is typed using a conditional type which became expensive to
compute with this intersection type. As a workaround, the original
`init` property is explicitly omitted which avoids the performance
cliff. This brings down the compile time by 15s.
