Enable mask movement for VCOND_EXPR under avx512f for
128/256-bit vector when integer mask is available.

* config/i386/sse.md
(*<avx512>_cmp<mode>3<mask_scalar_merge_name><round_saeonly_name>,
*<avx512>_cmp<mode>3<mask_scalar_merge_name>,
*<avx512>_ucmp<mode>3<mask_scalar_merge_name>,
*<avx512>_ucmp<mode>3<mask_scalar_merge_name>): New.
* config/i386/i386.c (ix86_print_operand): New operand substitution.
* config/i386/i386-expand.c (ix86_valid_mask_cmp_mode):
New function.
(ix86_expand_sse_cmp): Relax condition for integer mask from
512-bit vector to all 128/256/512-bit vector. Delete code gen
for avx512f compare patterns since we have generic pattern now.
(ix86_expand_sse_movcc): Adjust condition and codegen for
maskcmp.
(ix86_expand_int_sse_cmp): Don't canonicalize the comparison
when corresponding vector compare is available.
