re PR target/92908 (wrong code with -Og -fno-tree-fre -mavx512bw and vector compare)
PR target/92908
* simplify-rtx.c (simplify_relational_operation): Punt for vector
cmp_mode and scalar mode, if simplify_relational_operation returned
const_true_rtx.
(simplify_const_relational_operation): Change VOID_mode in function
comment to VOIDmode.
* gcc.target/i386/avx512bw-pr92908.c: New test.
