Asger Feldthaus f42a0ef25c dart2js cps: Always use interceptors and type tags for 'is' checks.
"x is Foo" will become getInterceptor(x).$isFoo

Testing against a type with type arguments is still a giveup().

This test always works, but is not very fast. For instance, testing
against an int should be "typeof x === 'number' && Math.floor(x) === x".

Following an offline discussion with Karl, the plan is to rewrite
'is'-checks to more fine-grained tests in a CPS optimization pass,
probably the type propagator.

Concretely, we plan to introduce IR nodes like TypeOfTest, FloorTest,
InstanceofTest, etc, which optimization phases can introduce under the
right circumstances. That way, the code generation phase remains simple.

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 dartanalyzer" test if
the assignment generates a static type warning.
