	*<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.
