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.

d482f55af1 Adjust the scavenge register spilling to allow the target to choose an
appropriate restore location for the spill as well as perform the actual
save and restore.

The Thumb1 target uses this to make sure R12 is not clobbered while a spilled
scavenger register is live there.

	ldr r0, LCPI1_0
	bl _printf
	ldr r0, [sp]
	mov sp, r7
	ldmsp! sp!, {r7, pc}

Note the unhappy ldm/stm because of modifiers being ignored.

172862a2a7 remove strings from instructions who are never asmprinted.
All of these "subreg32" modifier instructions are handled
explicitly by the MCInst lowering phase.  If they got to
the asmprinter, they would explode.  They should eventually
be replace with correct use of subregs.
