IBM Z: Fix address of operands will never be NULL warnings
Since a recent enhancement of -Waddress a couple of warnings are emitted
and turned into errors during bootstrap:
gcc/config/s390/s390.md:12087:25: error: the address of 'operands' will never be NULL [-Werror=address]
12087 | "TARGET_HTM && operands != NULL
build/gencondmd.c:59:12: note: 'operands' declared here
59 | extern rtx operands[];
| ^~~~~~~~
Fixed by removing those non-null checks.
gcc/ChangeLog:
* config/s390/s390.md ("*cc_to_int", "tabort", "*tabort_1",
"*tabort_1_plus"): Remove operands non-null check.
