X87:  Externalize deoptimization reasons.

port 2491a639bf46da4bfdcf65329305ee3053aa5fec (r26463)

original commit message:

   Externalize deoptimization reasons.
   1) The hardcoded strings were converted into DeoptReason enum.

   2) Deopt comment were converted into a pair location and deopt reason entries so
      the deopt reason tracking mode would less affect the size of the RelocInfo table and heap.

   3) DeoptReason entry in RelocInfo reuses kCommentTag value and generates short entry in RelocInfo table.
