Add runtime and native entry tags
...
- Split runtime and native entry tags.
- Set runtime / native entry address as vm tag in stubs.
- Add reverse native entry resolver (pc to name) to public API (breaking change).
- Hookup reverse resolver for standalone VM (io + bootstrap + builtin natives).
- Runtime entries are registered with tags.
- Profiler queries for tag names via the reverse native entry resolver.
- Profiler outputs named entry tags as children under parent tag (runtime or native).

Renamed Zone->StackZone, BaseZone->Zone, in preparation for changing isolate->get_zone() to return what was called the BaseZone instead of its wrapper. The GetBaseZone() methods were not renamed, to help the next CL.

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.

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.
