First step toward deoptimization using deoptimization info: splits deoptimization into two steps: copy frame to buffer, fill unoptimized frame from buffer. The only changes in the frame are the return address and the PC marker.
Second step will add deoptimization info 'instructions' that will fill the unoptimized frames using the saved registers and frame data.

- Use NoHandleScope in leaf methods
- have a no parameter constructor for NoHandleScope so that we can use that
in optimized mode when the Isolate is not available.

Rework leaf calls as just simple C calls with a signature and not the NativeArgumentDescriptor.

Add support for leaf runtime calls
- use a NoGCScope around these calls
- do not save and restore exit frame info, context register etc.
- Do not create a zone and handlescope by default

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.
