The ELF ABI specifies F1-F8 registers as argument registers for double, not
...
F1-F10. This affects only ELF, not MachO.

Fix a bug which caused us to never be able to use signed comparisons for
...
equality comparisons of a constant. This allows us to codegen the 'sintzero'
loop in PR1288 as:
LBB1_1: ;cond_next
li r4, 0
addi r2, r2, 1
stw r4, 0(r3)
addi r3, r3, 4
cmpwi cr0, r2, -1
bne cr0, LBB1_1 ;cond_next
instead of:
LBB1_1: ;cond_next
addi r2, r2, 1
li r4, 0
xoris r5, r2, 65535
stw r4, 0(r3)
addi r3, r3, 4
cmplwi cr0, r5, 65535
bne cr0, LBB1_1 ;cond_next
This implements CodeGen/PowerPC/compare-simm.ll, and also cuts 74
instructions out of kc++.
