I'm not sure about which SIMD instructions for amd64 are missing from Go 1.11 assembler.

Only these come to mind:

Some legacy MMX instructions
AMD-specific extensions

AFAIK, AVX1, AVX2 and AVX-512 were covered completely in Go 1.11 release.
(One can use https://github.com/golang/go/blob/master/src/cmd/internal/obj/x86/avx_optabs.go or https://github.com/golang/go/blob/master/src/cmd/internal/obj/x86/anames.go as a reference.)

Thanks in advance.
