This change introduces two new pragmas:
* `@pragma('vm:never-inline')`
* `@pragma('vm:prefer-inline')`
These replaces the old way of specifying AlwaysInline or NeverInline
annotations when the (now removed) --enable-inlining-annotations flag
was used.

Reason for revert: This CL seems to depend on constant_update_2018 flag being turned on by default. The CL that turns on constant_update_2018 has been reverted, so this CL is also being reverted.

This makes it an actual Pub package like most other code inside the SDK
repo. The main goal is to make it easier to write tests for the test
runner itself.
This change:
- Moves all of the code from tools/testing/dart/ over to
pkg/test_runner. Most of it ends up under test_runner/lib/src.
- Move tools/testing/dart/main.dart to
pkg/test_runner/bin/test_runner.dart.
- Move standalone_2/io/test_runner_test.dart to
pkg/test_runner/test/test_runner_test.dart. I don't think it currently
works, but it wasn't being run in its old location either.
- Add test_runner to the analysis-server bot. This ensures the
test_runner package is static error clean.
- Remove standalone_2/io/test_runner_analyze_test.dart which used to
attempt to do the above and is no longer needed.
- Update test.py to look for the test runner at its new location.
- Add test_runner to the repo .packages file and remove the weird
test_dart pseudo-package. (I think this fixes #35279.)
- Remove status file entries for the removed standalone_2 tests.
There are no code changes to the test runner itself aside from fixing
up import paths.

A field/function annotated with this pragma must be guaranteed to not
return `null` at runtime.
Make use of this non-nullable annotation in the VM's type propagator.
Annotates the "_TypedListView._typedData" field to ensure the VM knows it
returns a non-nullable _TypedListView.
Furthermore annotates methods on the integer implementation. Those particular
methods are recognized methods with a "dynamic" return type. This caused
the type propagator to use CompileType::Dynamic() as result type. Since a
previous CL started to only utilize the annotated type if it is better than
"dynamic" more integer operations got handled in-line, though with null-checks.
Annotating those methods to return non-null improves the in-line handling of
integer operations.
This improves dart-aot

Currently the @pramga('vm:exact-result-type') annotation only works if
the function is a recognized method. This change changes that to make
the VM just look if a function has the annotation (no matter if it's
also in the list of recognized methods or not).
Furthermore this CL lets the type propgagator use
@pragma('vm:exact-result-type') annotations to narrow the [CompileType]
set on [LoadFieldInstr]s.
Since the @pragma is a general feature, this CL moves the
`Function::FindPragma()` to `Library::FindPragma` (which is where any
other metadata lookup happens). We also let the `FindPragma` accept any
of Class/Function/Field objects.
Furthermore the `FindPragma()` function is fixed to handle the case
when the evaluation of the metadata results in an error.
In this case we simply claim to not have found a pragma annotation.

Previously we tried to rely on the assumption that all variables would be
boxed - so the machinery for setting correct catch-entry state only
supported tagged values and constants. However this both leads to worse code
and is not entirely correct assumption.
This also:
- renames various confusingly named classes: we move away from talking
about "catch entry state" to "catch entry moves" - because we only
record a subset of moves that needs to be performed and that does
not describe the whole state;
- refactors a bunch of associated code to be more readable and maintainable;
- adds documentation about catch implementation in optimized code
to runtime/docs/compiler;
