The test case works on S/390 too, but only with -march=z13 or later
(i.e. if Gcc can make use of hardware vector support). Otherwise the

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.
