Currently, based on the file names it's not quite clear whether
a given `.spec.ts` file runs benchmark perf or benchmark e2e
functionality tests. To disambiguate these, we use new file
suffixs. i.e. `e2e-spec.ts` and `perf-spec.ts`.
PR Close#34753
Currently we run all benchmark perf tests in CircleCI. Since we do not
collect any results, we unnecessarily waste CI/RBE resources. Instead,
we should just not run benchmark perf tests in CI, but still run the
functionality e2e tests which ensure that benchmarks are not broken.
We can do this by splitting the perf and e2e tests into separate
files/targets.

There are different `DebugNode`/`DebugElement` implementations (and
associated helper functions) for ViewEngine and Ivy. Additionally, these
classes/functions, which are defined inside the `core` package, are
imported by the `platform-browser` package.
Previously, this code was not tree-shaken as expected in Ivy. #30130
partially addressed the issue, but only for the case where `core` and
`platform-browser` end up in the same closure after webpack's scope
hoisting. In cases where this is not the case, our webpack/terser based
tooling is not capable of tree-shaking it.
This commit fixes the problem, by ensuring that the code retained in Ivy
mode (due to the cross-package import) does not unnecessarily reference
`DebugNode`/`DebugElement`, allowing the code to be tree-shaken away.
This results in a 7.6KB reduction in the size of the main angular.io
bundle.

In #34955, we switched to Node.js v12 on master and 9.0.x. This causes
the `aio_monitoring_job` CI job (which checks out files from the stable
branch; currently 8.2.x) to start failing yarn's engines check (since
the 8.2.x branch expects Node.js version <11).
Example failure: https://circleci.com/gh/angular/angular/602499
Since the job is expected to run with files from both the stable and the
master branches (and since the version of Node.js is not important
here), this commit uses the `--ignore-engines` option to prevent
failures due to Node.js version mismatch.
NOTE:
Typically, the stable and master branch are on the same Node.js version,
because related PRs land on both master and the patch branch. One
exception is during RC periods, when the stable branch is different than
the patch branch. These periods are usually short, but in the case of
9.0.0 the period has lasted several months causing the CI environments
between master and the stable branch to get significantly out-of-sync.

Component's decorator handler exposes `preanalyze` method to preload async resources (templates, stylesheets). The logic in preanalysis phase may throw `FatalDiagnosticError` errors that contain useful information regarding the origin of the problem. However these errors from preanalysis phase were not intercepted in TraitCompiler, resulting in just error message text be displayed. This commit updates the logic to handle FatalDiagnosticError and transform it before throwing, so that the result diagnostic errors contain the necessary info.

Previously we relied on this package being hoisted and available, which is error prone and it would
be just a matter of time before the build would break due rehoisting of deps upon future npm package.json
changes.
PR Close#34974
It's not clear how this ever worked (npm hoisting is a suspect though), but this dep is required because
one of the tests imports @babel/generator in the ts sources.
The lack of this dep is breaking builds on the master branch.

As part of the effort to tighten the API surface of
`TypeScriptServiceHost` in preparation for the migration to Ivy, I realized
some recently added APIs are not strictly needed.
They can be safely removed without sacrificing functionality.
This allows us to clean up the code, especially in the implementation of
QuickInfo, where the `TypeScriptServiceHost` is leaked outside of the
`LanguageService` class.
This refactoring also cleans up some duplicate code where the QuickInfo
object is generated. The logic is now consolidated into a simple
`createQuickInfo` method shared across two different implementations.

Previously we would write to class/style as strings `element.className` and `element.style.cssText`. Turns out that approach is good for initial render but not good for updates. Updates using this approach are problematic because we have to check to see if there was an out of bound write to style and than perform reconciliation. This also requires the browser to bring up CSS parser which is expensive.
Another problem with old approach is that we had to queue the DOM writes and flush them twice. Once on element advance instruction and once in `hostBindings`. The double flushing is expensive but it also means that a directive can observe that styles are not yet written (they are written after directive executes.)
The new approach uses `element.classList.add/remove` and `element.style.setProperty/removeProperty` API for updates only (it continues to use `element.className` and `element.style.cssText` for initial render as it is cheaper.) The other change is that the styling changes are applied immediately (no queueing). This means that it is the instruction which computes priority. In some circumstances it may result in intermediate writes which are than overwritten with new value. (This should be rare)
Overall this change deletes most of the previous code and replaces it with new simplified implement. The simplification results in code savings.

This change introduces several functions for manipulating items in an array in an efficient (binary search) way.
- `arraySplice` a faster version of `Array.splice()`.
- `arrayInsert` a faster version of `Array.splice(index, 0, value)`.
- `arrayInsert2` a faster version of `Array.splice(index, 0, value1, value2)`.
- `arrayInsertSorted` a way to insert a value into sorted list.
- `arrayRemoveSorted` a way to remove a value from a sorted list.
- `arrayIndexOfSorted` a way to find a value in a sorted list.
- `ArrayMap` Efficient implementation of `Map` as an `Array`.
- `arrayMapSet`, `arrayMapGet`, `arrayMapIndexOf`, and `arrayMapDelete` for manipulating `ArrayMap`s.

NOTE: This change must be reverted with previous deletes so that it code remains in build-able state.
This change deletes old styling code and replaces it with a simplified styling algorithm.
The mental model for the new algorithm is:
- Create a linked list of styling bindings in the order of priority. All styling bindings ere executed in compiled order and than a linked list of bindings is created in priority order.
- Flush the style bindings at the end of `advance()` instruction. This implies that there are two flush events. One at the end of template `advance` instruction in the template. Second one at the end of `hostBindings` `advance` instruction when processing host bindings (if any).
- Each binding instructions effectively updates the string to represent the string at that location. Because most of the bindings are additive, this is a cheap strategy in most cases. In rare cases the strategy requires removing tokens from the styling up to this point. (We expect that to be rare case)S Because, the bindings are presorted in the order of priority, it is safe to resume the processing of the concatenated string from the last change binding.

The change removes the fact that `NgStyle`/`NgClass` is special and colaborates with the `[style]`/`[class]` to merge its styles. By reverting to old behavior we have better backwards compatiblity since it is no longer treated special and simply overwrites the styles (same as VE)

The `computeStaticStyling` will be used for computing static styling value during `firstCreatePass`.
The function takes into account static styling from the template as well as from the host bindings. The host bindings need to be merged in front of the template so that they have the correct priority.

Parsing styling is now simplified to be used like so:
```
for (let i = parseStyle(text); i <= 0; i = parseStyleNext(text, i)) {
const key = getLastParsedKey();
const value = getLastParsedValue();
...
}
```
This change makes it easier to invoke the parser from other locations in the system without paying the cost of creating and iterating over `Map` of styles.
