Remove isolate pointer from context objects.
...
By moving all stubs that do runtime calls into the isolate
we don't need to cache the current isolate in each context
object.
This saves space on each context at the cost of duplicating stubs
in each isolate. Most stubs are already isolate-specific and the total number
of stubs is small enough for this to be a good trade-off.

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.
