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.

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.
