X87: Removed superfluous deopt for ROR on ia32.

port r24133. On X87 this check should be unnecessary too.
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.

Add a PRESUBMIT check that production code does not call test code
...
This is based on a regular expression matching anything in a namespace
ending in test, or a method containing the words ForTest, ForTesting,
for_test, or for_testing.
It is possible to blacklist entire directories or individual files.

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.

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.
