6fd04d829e Redesign of the internal type system. 
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.

Range types are now fully implemented.

efe4852d5d 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.

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.
