constraints.md (Yv): New constraint.

	* config/i386/constraints.md (Yv): New constraint.
	* config/i386/i386.h (VALID_AVX512VL_128_REG_MODE): Allow
	TFmode and V1TImode in xmm16+ registers for TARGET_AVX512VL.
	* config/i386/i386.md (avx512fvecmode): New mode attr.
	(*pushtf): Use v constraint instead of x.
	(*movtf_internal): Likewise.  For TARGET_AVX512VL and
	xmm16+ registers, use vmovdqu64 or vmovdqa64 instructions.
	(*absneg<mode>2): Use Yv constraint instead of x constraint.
	(*absnegtf2_sse): Likewise.
	(copysign<mode>3_const, copysign<mode>3_var): Likewise.
	* config/i386/sse.md (*andnot<mode>3): Add avx512vl and
	avx512f alternatives.
	(*andnottf3, *<code><mode>3, *<code>tf3): Likewise.

	* gcc.target/i386/avx512dq-abs-copysign-1.c: New test.
	* gcc.target/i386/avx512vl-abs-copysign-1.c: New test.
