b3c8359360 Fix some more NEON instruction encoding problems. 
Thanks to Johnny Chen for discovering the problem.

507df402b0 Leave some NEON instruction encoding bits unspecified instead of setting 
a default value of zero.  This is important for decoding the instructions.
Patch by Johnny Chen, with some changes from me, too.

1a49295eae Make TranslateX86CC return COND_INVALID instead of aborting when it 
encounters an OEQ or UNE comparison, and update its callers to check
for this return status and recover. This fixes a problem resulting from
the LowerOperation hooks being called from LegalizeVectorOps, because
LegalizeVectorOps only lowers vectors, so OEQ and UNE comparisons may
still be at large. This fixes PR5092.

scavenger register is live there.
