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.
