Besides addressing a fundamental flaw, this significantly simplifies

efe4852d5d X87: Removed superfluous deopt for ROR on ia32.

original commit message:
    Removed superfluous deopt for ROR on ia32.

    We only synthesize a ROR when we have an expression with a toplevel
    '|', which returns a signed value by definition, so deopting on
    negative values is not needed. ia32 was the only platform where this
    was done, all other didn't have the check.

803761a9f9 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.

269c46ee80 Simplify synthetic roots creation in heap snapshot 
The synthetic roots exist in every snapshot and there are no actual objects corresponding to them (there was attempt to create some virtual objects to reuse existing snapshot builder but it just complicated the things).

Previously synthetic root wouldn't have been added if it was empty. Current implementation always adds all synthetic roots in the snapshot no matter if they are empty or not.

7384467552 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.
