Type checking is broken

Use dartc_test to run:

bool foo(bool bar()) => bar();

bool bar() {}

main() {
  foo(bar);
}

with --enable_type_checks.

An error is thrown because the type of bar is not bool.

Just to be more clear, test.py —checked should turn on the type checks. Support was only added a few days ago. A fresh build and Ben got them to work in as much as they are supported.

bool foo(bool bar()) => bar();

bool baz() => true;

main() {
 Expect.equals(true, foo(baz));
}

When run with --enable_type_checks, this should produce no errors, but instead I get:

JAT, I believe that your commit, http://code.google.com/p/dart/source/detail?r=975 fixed this issue. Please reopen if that is not the case.
