Hal Finkel 891671afe5 Fix a register-class comparison bug in PPCCTRLoops ...

Thanks to Jakob for isolating the underlying problem from the
test case in r177423. The original commit had introduced
asymmetric copy operations, but these turned out to be a work-around
to the real problem (the use of == instead of hasSubClassEq in PPCCTRLoops).
