A recent change added UNSPEC to the CCMP patterns to stop combine optimizing
the immediate in a rare case. This requires a fix to the CCMP cost
calculation as the CCMP instruction with unspec is no longer recognized.
Fix the ccmp_1.c test by adding -ffinite-math-only so FCCMPE is emitted on
relational compares.

Add support for vector permute cost since various permutes can expand
into a complex sequence of instructions. This fixes major performance
regressions due to recent changes in SLP vectorizer (which now vectorizes
more aggressively and emits many complex permutes). Set the cost to > 1
for all microarchitectures so that the number of permutes is usually zero
and regressions disappear.

Several instructions disassemble a zero immediate as wzr/xzr due to
using a register operand in the disassembly. Avoid this by removing
the register operand.

It turns out the 's' output modifier is used in some glibc math code,
and is in an installed header even. So let's put it back, it is much

(It is also being fixed for glibc.)
