Hello,
This patch supports AVX-512's vshufpd insns.

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

Is it ok for trunk?

gcc/
	* config/i386/sse.md
	(define_expand "avx_shufpd256<mask_expand4_name>"): Add masking.
	(define_insn "avx_shufpd256_1<mask_name>"): Ditto.
	(define_expand "sse2_shufpd<mask_expand4_name>"): Ditto.
	(define_insn "sse2_shufpd_v2df_mask"): New.

Thanks, K
