This can be downleveled in CommonJS to either:
```
__export(require('some-import'));

or
```
var someImport = require('some-import');
__export(someImport);

Previously we only supported the first downleveled version.
This commit adds support for the second version.

Previously individual properties of the src bundle program were
passed to the reflection host constructors. But going forward,
more properties will be required. To prevent the signature getting
continually larger and more unwieldy, this change just passes the
whole src bundle to the constructor, allowing it to extract what it
needs.

When a HTML Ast containing an Attribute node is converted to a Template Ast,
the attribute node might get dropped from the Template Ast path.
This is because the AttrNode is not even in the Template Ast to begin with.
In this case, we manually fix the path by converting the Attribute node
to a AttrAst node and appending it to the path.
This allows the `ExpressionVisitor` to properly visit the leaf node in the
TemplateAst path. We no longer need to visit the `Element` and look for
attributes.

Prior to this change, the ExpressionChangedAfterChecked error thrown in Ivy was missing useful information that was available in View Engine, specifically: missing property name for proprty bindings and also the content of the entire property interpolation (only a changed value was displayed) if one of expressions was changed unexpectedly.

The `aio_monitoring_stable` CI job is triggered as a cronjob on the
master branch and its purpose is to run some e2e tests against the
deployed stable version of the docs web-app at https://angular.io/. In
order for the tests to be compatible with the deployed version of the
web-app (which gets deployed from the stable branch), the stable branch
is checked out in git as part of the CI job.
Previously, we only checked out the `aio/` directory from the stable
branch, leaving the rest of the code at master. This doesn't matter as
long as the commands used to run the tests do not rely on code outside
of `aio/`. However, it turns out that there _is_ code outside of `aio/`
that affects the executed commands: It is our vendored version of yarn
(in `third_party/github.com/yarnpkg/`), which overwrites the global yarn
installed on the docker image on CI and must match the version range
specified in `aio/package.json > engines`.
Using the yarn version checked out from the master branch with the
`aio/` code checked out from the stable branch can lead to failures
such as [this one][1].
This commit fixes the problem by checking out both the `aio/` and
`third_party/github.com/yarnpkg/` directories from the stable branch and
re-running the steps to overwrite the global yarn executable with our
own version from `third_party/github.com/yarnpkg/`. This ensures that
the version of yarn used will be compatible with the version range
specified in `aio/package.json > engines`.
NOTE:
We cannot checkout everything from the stable branch, since the CI
config (`.circleci/config.yml` from the master branch) may try to run
certain scripts (such as `.circleci/get-vendored-yarn-path.js`) that are
not available on the stable branch. Therefore, we should only check out
the necessary bits from the stable branch.

This commit adds three previously missing validations to

3. It checks that classes are declared in at most one NgModule.

NgModel internally coerces any arbitrary value that will assigned
to the `disabled` `@Input` to a boolean. This has been done to
support the common case where developers set the disabled attribute
without a value. For example:
```html
<input type="checkbox" [(ngModel)]="value" disabled>
```
This worked in View Engine without any errors because inputs were
not strictly checked. In Ivy though, developers can opt-in into
strict template type checking where the attribute would be flagged.
This is because the `NgModel#isDisabled` property type-wise only
accepts a `boolean`. To ensure that the common pattern described
above can still be used, and to reflect the actual runtime behavior,
we should add an acceptance member that makes it work without type
checking errors.
Using a coercion member means that this is not a breaking change.

Given the following HTML and cursor position:
```
<div c|></div>
^ cursor is here
```
Note that the cursor is **after** the attribute `c`.
Under the current implementation, only `Element` is included in the
path. Instead, it should be `Element -> Attribute`.
This bug occurs only for cases where the cursor is right after the Node,
and it is because the `end` position of the span is excluded from the search.
Instead, the `end` position should be included.

The ordering matters because we don't currently throw if multiple

In the TransitionAnimationEngine we keep track of the existing elements with animations and we clear the cached data when they're removed. We also have some logic where we transition away the child elements when a parent is removed, however in that case we never cleared the cached element data which resulted in a memory leak. The leak is particularly visible in Material where whenever there's an animated overlay with a component inside of it that has an animation, the child component would always be retained in memory.

Currently we only run Saucelabs on PRs using the legacy View Engine
build. Switching that build to Ivy is not trivial and there are various
options:
1. Updating the R3 switches to use POST_R3 by default. At first glance,
this doesn't look easy because the current ngtsc switch logic seems to
be unidirectional (only PRE_R3 to POST_R3).
2. Updating the legacy setup to run with Ivy. This sounds like the easiest
solution at first.. but it turns out to be way more complicated. Packages
would need to be built with ngtsc using legacy tools (i.e. first building
the compiler-cli; and then building packages) and View Engine only tests
would need to be determined and filtered out. Basically it will result in
re-auditing all test targets. This is contradictory to the fact that we have
this information in Bazel already.
3. Creating a new job that runs tests on Saucelabs with Bazel. We specify
fine-grained test targets that should run. This would be a good start
(e.g. acceptance tests) and also would mean that we do not continue maintaining
the legacy setup..
This commit implements the third option as it allows us to move forward
with the general Bazel migration. We don't want to spend too much time
on our legacy setup since it will be removed anyway in the future.

We keep a version of yarn in the repo, at
`third_party/github.com/yarnpkg/`. All CI jobs should use that version
for consistency (and easier updates).
Previously, the Windows jobs did not use the local version. They used
the version that came pre-installed on the docker image that we used.
This made it more difficult to update the yarn version (something that
we might want to do independently of updating other dependencies, such
as Node.js).
This commit fixes this by setting up the Windows CI jobs to also use the
local, vendored version of yarn.

We keep a version of yarn in the repo, at
`third_party/github.com/yarnpkg/`. All CI jobs (including Windows ones)
should use that version for consistency (and easier updates). The path
to the actual `yarn.js` script, however, changes depending on the
version (e.g. `third_party/github.com/yarnpkg/v1.21.1/...`).
(NOTE: The Windows jobs are currently not using this local version, but
that should be fixed in a subsequent commit.)
Previously, when updating the local version of yarn, we would
potentially have to update the path in several places.
This commit addresses the problem by adding a Node.js script that infers
the correct path. The script can be used in all places where we need to
use the local version of yarn (including both Linux and Windows CI
jobs), thus eliminating the need to update the path in several places.

When we log DI errors we get the name of the provider via `SomeClass.name`. In IE functions that inherit from other functions don't have their own `name`, but they take the `name` from the lowest parent in the chain, before `Function`.

The way definitions are added in JIT mode is through `Object.defineProperty`, but the problem is that in IE10 properties defined through `defineProperty` won't be inherited which means that inheriting injectable definitions no longer works.

This isn't ideal, but it should only be required until v10 where we'll no longer support inheriting injectable definitions from undecorated classes.

In `DebugElement.attributes` we return all of the attributes from the underlying DOM node.

While sanitizing on browsers that don't support the `template` element (pretty much only IE), we create an inert document and we insert content into it via `document.body.innerHTML = unsafeHTML`. The problem is that IE appears to parse the HTML passed to `innerHTML` differently, depending on whether the element has been inserted into a document or not. In particular, it seems to split some strings into multiple text nodes, which would've otherwise been a single node. This ended up throwing off some of the i18n code down the line and causing a handful of failures. I've worked around it by creating a new inert `body` element into which the HTML would be inserted.

A quirk of the Angular template parser is that when parsing templates in the
"default" mode, with options specified by the user, the source mapping
information in the template AST may be inaccurate. As a result, the compiler
parses the template twice: once for "emit" and once to produce an AST with
accurate sourcemaps for diagnostic production.
Previously, only the first parse was performed during analysis. The second
parse occurred during the template type-checking phase, just in time to
produce the template type-checking file.
However, with the reuse of analysis results during incremental builds, it
makes more sense to do the diagnostic parse eagerly during analysis so that
the work isn't unnecessarily repeated in subsequent builds. This commit
refactors the `ComponentDecoratorHandler` to do both parses eagerly, which
actually cleans up some complexity around template parsing as well.

Avoids the usage of array destructuring, as it introduces calls to
a `__values` helper function in ES5 that has a relatively high
performance impact. This shaves off roughly 130ms of CPU time for a

The template parser has a certain interpolation config associated with
it and builds a regular expression each time it needs to extract the
interpolations from an input string. Since the interpolation config is
typically the default of `{{` and `}}`, the regular expression doesn't
have to be recreated each time. Therefore, this commit creates only a
single regular expression instance that is used for the default
configuration.
In a large compilation unit with big templates, computing the regular
expression took circa 275ms. This change reduces this to effectively
zero.
