	v4fnmaddps
	v4fnmaddss
	vaesdec
	vaesdeclast
	vaesenc
	vaesenclast
	vcvtne2ps2bf16
	vcvtneps2bf16
	vdpbf16ps
	gf2p8affineinvqb
	vgf2p8affineinvqb
	gf2p8affineqb
	vgf2p8affineqb
	gf2p8mulb
	vgf2p8mulb
	vp2intersectd
	vp2intersectq
	vp4dpwssd
	vp4dpwssds
	vpclmulqdq
	vpcompressb
	vpcompressw
	vpdpbusd
	vpdpbusds
	vpdpwssd
	vpdpwssds
	vpexpandb
	vpexpandw
	vpopcntb
	vpopcntd
	vpopcntq
	vpopcntw
	vpshldd
	vpshldq
	vpshldvd
	vpshldvq
	vpshldvw
	vpshldw
	vpshrdd
	vpshrdq
	vpshrdvd
	vpshrdvq
	vpshrdvw
	vpshrdw
	vpshufbitqmb

For information about the instructions, refer Intel SDM May 2019
(325462-070US) and Intel Architecture Instruction Set Extensions May
2019 (319433-037).

The instruction decoding can be tested using the perf tools' "x86
instruction decoder - new instructions" test e.g.

  $ perf test -v "new " 2>&1 | grep -i 'v4fmaddps'
  Decoded ok: 62 f2 7f 48 9a 20                   v4fmaddps (%eax),%zmm0,%zmm4
  Decoded ok: 62 f2 7f 48 9a a4 c8 78 56 34 12    v4fmaddps 0x12345678(%eax,%ecx,8),%zmm0,%zmm4
  Decoded ok: 62 f2 7f 48 9a 20                   v4fmaddps (%rax),%zmm0,%zmm4
  Decoded ok: 67 62 f2 7f 48 9a 20                v4fmaddps (%eax),%zmm0,%zmm4
  Decoded ok: 62 f2 7f 48 9a a4 c8 78 56 34 12    v4fmaddps 0x12345678(%rax,%rcx,8),%zmm0,%zmm4
  Decoded ok: 67 62 f2 7f 48 9a a4 c8 78 56 34 12 v4fmaddps 0x12345678(%eax,%ecx,8),%zmm0,%zmm4
