X87: Refactoring InterfaceDescriptors away from code-stubs.h

Browse Source 
port r23515.

original commit message:
  Refactoring InterfaceDescriptors away from code-stubs.h

  Clean up and create seperation between the concept of a call descriptor and a
  code stub interface descriptor. The former is just concerned with how to call,
  but the latter has many extra hints related to code generation and deoptimization
  for the implementation of a particular code stub.
