Collects files from `package:async_helper` and `tests/language`
that are generally useful, so that all test-related helpers are
in `package:expect`.
Moves the two libraries from `package:async_helper` into `package:expect`,
and the `tests/language/static_type_helper.dart` file too.
Deprecates `async_minitest.dart`, to follow `minitest.dart`,
expecting the Flutter use of it to have been fixed to not break
on deprecation (I believe Flutter no longer breaks builds on deprecations at all).
Patch 1 is the actual change.
Patch 2+4+8 is changing all existing references to the files.
Patch 6 ignores deprecation in files still using `async_minitest.dart`.
3+5+7+9 are updating this text to make the numbers match.
Then it's just test-expectations and small tweaks from there.

- Add SSA HArrayFlags{Check,Get,Set} instructions to check for
fixed-length and unmodifiable JSArray and JavaScript typed data
instances.
- Add optimizations to remove redundant checks.
- Added HOutputConstrained interface for instructions that must have
the input and output in the same JavaScript variable. This
generalizes some code generation logic already applied to HCheck.

Late fields start out holding a sentinel value and after they are initialized or assigned, never hold a sentinel value again.
This CL implements some removal of checks and loads based on this monotonic behaviour.
On two large Dart Angular apps, this reduces the number of late-instance-field checks by ~25%.
One app is 0.44% smaller, the other is 0.98% smaller.
The optimization_test.dart no longer forces `--disable-inlining` because that prevents the inlining that exposes the optimization opportunities.
Most tests already use `@pragma('dart2js:noInline')` to prevent inlining where relevant.

The single-entry / single-exit patterns of the CFG prevent inlined
throw statements and throw expressions from having exit edges like a
statement-level throw. If the join block is not reachable on one path
of a diamond, the condition can be substituted as if the join is on
the other path.

Index bounds checks are now added as part of lowering `[]`, `[]=` and
`removeLast()` rather that being added later in a separate pass.
To know when to add checks, new trust/check annotations have been
added:
@pragma('dart2js:index-bounds:trust')
@pragma('dart2js:index-bounds:check')
These default according to the `--trust-primitives` command-line
option.
In order to consult the annotations, the enclosing context of the
method call is tracked. This allows annotations to be applied correctly
when several methods with different annotations are inlined.
