fixes#30495 - optimize subtype cache
fixes#30464 - optimize `is List`
Additional changes:
- optimize double type checks
- optimize Object type checks
- optimize FutureOr<T> checks
- optimize interface checks for some dart:core and dart:async types (List, Map, Iterable, Future, Stream, and StreamSubscription )
- optimize checks for generic class default instantiations and exact instantiation (e.g. `C<dynamic>` on any instance `C<T>`, and `C<T> on an instance of C<T>`
- optimize checks for native types
- optimize getReifiedType
- optimize dcall/dsend/dput checks to use faster Type._check pattern
- optimize instanceOf/cast functions by moving special cases to appropriate types
- optimize Object.runtimeType
- optimize JS interop type checks
- optimize all function type checks
There's more we can do (especially for class/interface types) but this should cover a lot of cases.

Eliminate numerous type checks not needed in strong mode. Use
private nullability annotations instead of inline JS to mark known
non-null variables, and to make the compiler generate null checks
for null checked variables. Use nullability annotations and code refactoring to
remove redundant null checks and to move checks out of loops.

This is the original CL plus status file fixes.
Disables auto-generated function_type tests that are not working for the Dart 2 runtime behavior, and filed #30462 to track. Also removes the separate status that was skipping these tests in DDC when $checked was unset. $checked is not a thing for Dart 2, and DDC test status should never depend on it.
This reverts commit 1b0b1a4913.

This is an attempt to get DDC's bot (https://travis-ci.org/dart-lang/sdk) green and restore test coverage, without affecting the Analyzer --strong buildbot. DDC and Analyzer can generally use the same status entries, as they are running nearly identical strong mode analysis. This fixes DDC's test builder to understand status codes in the same way analyzer does, as that was causing mismatch in statuses.
This does not fix the problem that we're skipping tests instead of recording the status. So there is a bit of test coverage lost, but it restores most of DDC's coverage. We can tackle the skips either in a follow up, or as we migrate tests from *_strong to *_2.
This is a partial revert of "Revert status file changes from 58a6227198d2aa927df19f1b4862f8d0017d6da4" in commit 7be946cf3d.

This only handles compile time errors & compiler crashes. It does not yet support status files at runtime, that is still hard coded in language_tests.js. Some preliminary support for runtime status is there, but it's not enabled yet.
This also updates *_strong.status to reflect current test behavior. It looks like those files have not been triaged in a while.

A few more passes, but perhaps one regression:

Previously, the string set up by the embedder was eagerly passed to
Uri.parse during Isolate startup. This is expensive both in time and
memory footprint. This CL causes Uri.parse() to be called only
when needed. This change will allow reducing the memory footprint
of Fuchsia's Dart content handler on hello world by ~1MB.

Include migrated "_2" test directories in DDC's codegen_test.
This required a couple of other changes too:
- I renamed "not_yet_strong_tests.dart" to "compile_error_tests.dart"
because it includes some tests that have been made strong mode clean,
but still generate static errors due to bugs in analyzer or ddc.
- Reworded the test failure messages to take the above into account.
- I cleaned up the failure reporting code a bit. There was some
redundancy and unreachable code.
- Triaged the "_2" tests to mark the ones that are failing at compile
time or runtime appropriately. Good news! The big integers tests
compile now! Of course, they don't actually *run* correctly on the
web...
also fixes various bugs:
* setters now use the correct memberName symbol, fixes#30223
* object members work for callable classes, fixes#30213
* some test fixes to work in strong mode
* a few other small cleanups (e.g. obsolete `dart.list` is removed)
