i386.md (*movoi_internal_avx): Set mode attribute to XI for SSE constm1 operands and TARGET_AVX512VL. 

* config/i386/i386.md (*movoi_internal_avx): Set mode attribute to XI
	for SSE constm1 operands and TARGET_AVX512VL.
	(*movti_internal): Ditto.
	(*mov<mode>_or): Use constm1_operand predicate.
	* config/i386/sse.md (*mov<mode>_internal): Set mode attribute to XI
	for SSE vector_all_ones operands and TARGET_AVX512VL.
	* config/i386/predicates.md (constm1_operand): New predicate.
	* config/i386/i386.c (standard_sse_constant_opcode): Simplify
	emission of constant -1 load.
