X87: Propagate Deopt reason to cpu-profiler

port 86cae1633caa31f2225b6932850fb13d3a21cf59 (r26545)

original commit message:

  1) Deoptimizer::Reason was replaced with Deoptimizer::DeoptInfo
     because it also has raw position. Also the old name clashes with DeoptReason enum.

  2) c_entry_fp assignment call was added to EntryGenerator::Generate
     So we can calculate sp and have a chance to record the stack for the deopting function.
     btw it makes the test stable.

  3) new kind of CodeEvents was added to cpu-profiler

  4) GetDeoptInfo method was extracted from PrintDeoptLocation.
     So it could be reused in cpu profiler.
