      [Interpreter] Add support for cpu profiler logging. · cb29f9cd
      rmcilroy authored 
      Adds support for cpu profiler logging to the interpreter. Modifies the
the API to be passed AbstractCode objects instead of Code objects, and
adds extra functions to AbstractCode which is required by log.cc and
cpu-profiler.cc.

The main change in sampler.cc is to determine if a stack frame is an
interpreter stack frame, and if so, use the bytecode address as the pc
for that frame. This allows sampling of bytecode functions. This
requires adding support to SafeStackIterator to determine if a frame is
interpreted, which we do by checking the PC against pre-stored addresses
for the start and end of interpreter entry builtins.

Also removes CodeDeleteEvents which are dead code and haven't
been reported for some time.

Still to do is tracking source positions which will be done in a
followup CL.

      Remove the dependency of Zone on Isolate · c7b09aac
      danno authored 
      Along the way:
- Thread isolate parameter explicitly through code that used to
  rely on getting it from the zone.
- Canonicalize the parameter position of isolate and zone for
  affected code
- Change Hydrogen New<> instruction templates to automatically
  pass isolate

      MIPS: CodeStubs contain their corresponding Isolate* now. (part 1) · bb1abb7f
      plind44@gmail.com authored 
      Port r20919 (aa51355)

Original commit message:
This is a purely mechanical change, adding an Isolate* to the CodeStub
constructor and a corresponding field plus a getter. A few methods in
CodeStub and its subclasses can be simplified now, but this is done in
a separate CL.

The underlying reason apart from simplicity is that deep down in the
call chain we need to detect if the serializer is active or not. This
information will be part of the Isolate, not a global variable with
funky synchronization primitives around it (which is fundamentally
wrong and the underlying cause for race conditions and a catch-22
during initialization).
