X87: Further improve deopt reason output

port r24123.  R24123 does not cover all required code change in X87.

original commit message:
   Further improve deopt reason output.
   * Make the detailed deopt reason mandatory on x64, other platforms will
     follow in separate CLs.

   * Extracted and improved jump table entry sharing logic: When --trace-deopt
     is on, we get separate entries for different deopt reasons. This enables
     us to distinguish the several reasons single instructions can have.

   * Don't emit superfluous jump table comments: The bailout ID is still visible,
     and the jump table entry number is not interesting (but easy to determine
     if really needed).

   * Unify the internal name of the jump table member across platforms.
