Fold comparisons against a constant nan, and optimize ORD/UNORD
comparisons with a constant. This allows us to compile isnan to:
_foo:
fcmpu cr7, f1, f1
mfcr r2
rlwinm r3, r2, 0, 31, 31
blr
instead of:
LCPI1_0: ; float
.space 4
_foo:
lis r2, ha16(LCPI1_0)
lfs f0, lo16(LCPI1_0)(r2)
fcmpu cr7, f1, f0
mfcr r2
rlwinm r3, r2, 0, 31, 31
blr
