port d1c28849(r33873)

  original commit message:
  Moves InterpreterAssembler out of the compiler directory and into the
  interpreter directory. Makes InterpreterAssembler as subclass of
  CodeStubAssembler.

  As part of this change, the special bytecode dispatch linkage type
  is removed and instead we use a InterfaceDispatchDescriptor and
  a normal CodeStub linkage type.

  Removes a bunch of duplicated logic in InterpreterAssembler and
  instead uses the CodeStubAssembler logic. Refactors Interpreter
  with these changes.

  Modifies CodeStubAssembler to add the extra operations required
  by the Interpreter (extra call types, raw memory access and some extra
  binary ops). Also adds the ability for subclasses to add extra
  prologue and epilogue operations around calls, which is required
  for the Interpreter.
