The compactor copies all live objects in old space to fresh pages, places forwarding pointers in the old objects, forwards all the pointers, then frees the old pages. This has a high space overhead. It is not meant for use in production, but meant to test that the VM is properly set up to handle old-space objects moving.
Large page objects and instruction objects are not moved.

This moves Http code into dart:_http. dart:io then imports and
re-exports dart:_http. This is the first stage of moving
dart:_http into its own pub package.
This CL was reverted due to a failure in the Flutter engine build
which happened due to an incomplete change in gen_snapshot.cc, and to
update sdk/lib/libraries.yaml and sdk/lib/libraries.json

Reverting for broken Flutter build and kernel platform compilation test. It looks like the new _http library is missing from various snapshots. Not sure why this didn't fail locally.
This reverts commit ac9ff3f3af.

Fairly simple block, with only minor changes made to lib_2/mirrors tests
needed for strong mode compliance.

There are far too many files here to review everyone carefully.
Spot checking most of the diffs look good as test code is generally written
with less care than application code so lots of ugly formatting get through.
If people notice files where the automated formatting bothers them feel free
to comment indicating file names and I'll move spaces within comments to make
the formatting cleaner and use comments to force block formatting as I have
done for other case where formatting looked bad.

Update all tests
Support //# multitests for better dartfmt compatibility and fewer multitest false positives
All files under tests were manually updated with
find . -iregex '.*\.dart$' -print0 | xargs -0 perl -pi -e 's/(\S\s+)\/\/\/ /$1\/\/# /'
For now both old and new styles are allowed to accommodate CO19 tests.

Add fatal from dart:_internal to the blacklist of functions we should
not invoke while fuzzing mirrors. Invoking it will not succeed.
Arguably, mirrors should not be able to see any of the members of
dart:_internal but that's a bigger implementation change and possibly
a breaking change.

Revert "Update Dartium status for passing test"
This reverts commit d71c70d56d.
Tests failing on dart2js and async_star_pause_test is
passing on Dartium. Need to think about how to update the
status files.

MirrorsUsed doesn't transitively include reflective information. However, it must still be able to create TypeMirrors for types that are used as return- or parameter types.
Initially, the patch checked that TypeMirrors had the correct number of arguments for generic types. This is now disabled.
A better approach would be to know if a class has full reflective information, or not. But this would require much bigger changes to the system.

* Basic implementation of reflecting generic types using dynamic list of type arguments
* Removed redundant expectation in test
* Added basic support for dynamic type arguments in reflectType of js_mirrors
* Fixes according to code review comments: major cleanup, added more test cases and updated docs
* Updated JS mirrors reflectType() to match behavior of VM implementation
* Terminate exception messages with a dot; Improved error handling for empty argument list and type checks;
* Use NumTypeParameters when checking provided argument list size
* Check if type arguments are malbounded; added test cases for typedefs and mixins
* Uncommented a test case
* Updated lib.status to mark some tests as failing in dart2js due to limitations in JS mirrors
* Fixed mixin test mock definition; updated configuration for tests requiring checked mode
* Handle nested generic types in type argument parsing (JS)
Add mirror regression test.
Adjust expectation of a mirror test.
Fix parser to mark current class as typedef before parsing signature.
Fix canonicalization of typedef function types (a typedef class can be the scope
class of more than one function type, even if not generic).
