Lasse R.H. Nielsen d509ddb3fa Use FutureOr more and make Future.sync return the resulting Future directly.
When the computation passed to Future.sync returns a Future of the correct type,
then it's returned directly instead of wrapping it again.
(Until strong mode, we have an extra case for when it returns a Future of an
incorrect type, but that will eventually be removed).

This should improve the performance of Future.sync a bit.

Also adds missing Zone intercept for when the Future.sync computation throws.

Updates documentation for Future.doWhile.

Run Existing Tests
==================

See the output of

  ../tools/test.py --help

for how to run tests.

See also

  https://code.google.com/p/dart/wiki/Building#Testing

for detailed examples.

Create New Tests
================

See comments above

  factory StandardTestSuite.forDirectory

in

  ../tools/testing/dart/test_suite.dart

for the default test directory layout. By default test-file names must
end in "_test.dart", but some test suites, such as ./co19, subclass
StandardTestSuite and override this default.

See comments at the beginning of

  ../tools/testing/dart/multitest.dart

for how to create tests that pass by failing with a known error. For
example,

  ...
  int x = "not an int"; /// 01: static type warning
  ...

as part of a test will only pass the "--compiler dart2analyzer" test if
the assignment generates a static type warning.
