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.

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.

Refactoring: Remove more legacy from release scripts.

- Remove an unused feature that allowed to check for required
  data before each script step.
- Use a relative path to the version file. In the production
  environment, this will point to the cwd/version_file, while
  in the test environment it is fake_cwd/version_file.

Made the detailed reason for deopts mandatory on ia32. Unified and improved things.

The number of different detail strings has been reduced a bit without
any loss of information. Furthermore, DoubleToI is a bit more
informative now. Tiny reason fixes.
