Hello,
This patch extends andnot and any_logic insn
patterns.

Bootstrapped.
AVX-512* tests on top of patch-set all pass
under simulator.

Is it ok for trunk?

gcc/
	* config/i386/sse.md
	(define_insn "<sse>_andnot<VF_128_256:mode>3<mask_name>"): Add masking,
	use VF_128_256 mode iterator and update assembler emit code.
	(define_insn "<sse>_andnot<VF_512:mode>3<mask_name>"): New.
	(define_expand "<any_logic:code><VF_128_256:mode>3<mask_name>"):
	Add masking, use VF_128_256 mode iterator.
	(define_expand "<any_logic:code><VF_512:mode>3<mask_name>"): New.
	(define_insn "*<any_logic:code><VF_128_256:mode>3<mask_name>"):
	Add masking, use VF_128_256 mode iterator and update assembler emit
	code.
	(define_insn "*<any_logic:code><VF_512:mode>3<mask_name>"): New.
	(define_mode_attr avx512flogicsuff): Delete.
	(define_insn "avx512f_<logic><mode>"): Ditto.
	(define_insn "*andnot<mode>3<mask_name>"): Update MODE_XI, MODE_OI,
	MODE_TI.
	(define_insn "<mask_codefor><code><mode>3<mask_name>"): Ditto.
