IBM Z: Restrict vec_cmp<m><n> on z13
Commit 5d9ade39b872 ("IBM Z: Fix PR97326: Enable fp compares in
vec_cmp") made it possible to create rtxes that describe signaling
comparisons on z13, which are not supported by the hardware. Restrict
this by using vcond_comparison_operator predicate.

* config/s390/vector.md: Use vcond_comparison_operator
predicate.
