* config/i386/i386-expand.c (ix86_expand_sse_cmp): Don't
generate integer mask comparison for 128/256-bits vector when
op_true/op_false is NULL_RTX or CONSTM1_RTX/CONST0_RTX. Also
delete redundant !maskcmp condition.
(ix86_expand_int_vec_cmp): Ditto but no redundant deletion
here.
(ix86_expand_sse_movcc): Delete definition of maskcmp, add the
condition directly to if (maskcmp), add extra check for
cmpmode, it should be MODE_INT.
(ix86_expand_fp_vec_cmp): Pass NULL to ix86_expand_sse_cmp's
parameters op_true/op_false.
(ix86_use_mask_cmp_p): New.

* g++.target/i386/avx512bw-pr98537-1.C: New test.
* g++.target/i386/avx512vl-pr98537-1.C: New test.

* gcc.target/i386/avx512vl-pr88547-1.c: Adjust testcase,
integer mask comparison should not be generated.
* gcc.target/i386/avx512vl-pr92686-vpcmp-1.c: This test is
used to guard code generation of integer mask comparison, but
for vector comparison to vector dest, integer mask comparison
is disliked, so detele this useless test.
* gcc.target/i386/avx512vl-pr92686-vpcmp-2.c: Ditto.
