X87: [compiler] Introduce initial StrictEqualStub.

  port 4acb492e145b39700bbbc36ff0da5830de50f814 (r34423)

  original commit message:
  Initial version of a new StrictEqualStub written as TurboFan code stub,
  that implements the full strict equality comparison and is usable for
  both TurboFan and Ignition (and soon for the generic CompareIC case
  too). The stub is not fully optimized yet, i.e. we still go to the
  runtime for string comparisons, but that'll be addressed in a follow-up
  CL.
