Besides addressing a fundamental flaw, this significantly simplifies
several aspects of the system.  The downside is a loss of precision
and a loss of algebraic properties.

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.

  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.

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.
