Simplify representation of stack frames. Remove the special types DartFrame/StubFrame and instead use StackFrame with methods IsDartFrame and IsStubFrame for frames representing Dart or Stub Code. This eliminates all the complexity that was added to ensure that we always see only one stub frame before hitting a dart frame during iteration.
...
Fixes bug 6380625 which was another case when we had two stub frames before hitting the dart frame.

Use null type argument vector instead of vector of Dynamic for a generic raw

type when possible.
Fix type finalization of type parameters (always finalize in the context of the
class being parameterized and not in the enclosing class where the type
parameter is used).

from a raw instantiator is not always raw).
Added printing of type argument vectors.

Do not count invocations but usage of a function, i.e., increment a function's counter at IC calls and at return operations in unoptimized code. (TODO: increment count at static calls as well). There is no checking at method entry any more. The function counter reporting is not measuring the invocation count but much more how much time we spend in a method. Removed counter at backward branches.

Add support for interrupting an isolate in the vm. Interrupts are
...
implemented by extending the existing support for stack overflow
checking in the vm. When an interrupt is scheduled for an isolate, we
overwrite the isolate's stack limit with a value guaranteed to cause a
stack overflow.
We support multiple kinds of interrupts, encoded in the low bits of
the stack limit.
Add Dart_InterruptIsolate and Dart_InterruptIsolateCallback to the
dart embedding api to allow the embedder to request and handle
interrupts.
Add EXPECT_SUBSTRING(needle, haystack) testing macro.
