i386-protos.h (standard_sse_constant_p): Add machine_mode argument.

i386-protos.h (standard_sse_constant_p): Add machine_mode argument.

	* config/i386/i386-protos.h (standard_sse_constant_p): Add
	machine_mode argument.
	* config/i386/i386.c (standard_sse_constant_p): Return 2 for
	constm1_rtx operands.  For VOIDmode constants, get mode from
	pred_mode.  Check mode size if the mode is supported by ABI.
	(standard_sse_constant_opcode): Do not use standard_constant_p.
	Strictly check ABI support for all-ones operands.
	(ix86_legitimate_constant_p): Handle TImode, OImode and XImode
	immediates. Update calls to standard_sse_constant_p.
	(ix86_expand_vector_move): Update calls to standard_sse_constant_p.
	(ix86_rtx_costs): Ditto.
	* config/i386/i386.md (*movxi_internal_avx512f): Use
	nonimmediate_or_sse_const_operand instead of vector_move_operand.
	Use (v,BC) alternative instead of (v,C). Use register_operand
	checks instead of MEM_P.
	(*movoi_internal_avx): Use nonimmediate_or_sse_const_operand instead
	of vector_move_operand.  Add (v,BC) alternative and corresponding avx2
	isa attribute.  Use register_operand checks instead of MEM_P.
	(*movti_internal): Use nonimmediate_or_sse_const_operand for
	TARGET_SSE.  Improve TARGET_SSE insn constraint.  Add (v,BC)
	alternative and corresponding sse2 isa attribute.
	(*movtf_internal, *movdf_internal, *movsf_interal): Update calls
	to standard_sse_constant_p.
	(FP constant splitters): Ditto.
	* config/i386/constraints.md (BC): Do not use standard_sse_constant_p.
	(C): Ditto.
	* config/i386/predicates.md (constm1_operand): Remove.
	(nonimmediate_or_sse_const_operand): Rewrite using RTX.
	* config/i386/sse.md (*<avx512>_cvtmask2<ssemodesuffix><mode>): Use
	vector_all_ones_operand instead of constm1_operand.
