Subject: [PATCH] Extend description of GOAMD=v4

This code is gated on GOAMD=v4, so we should include that case in the wiki.

 Setting, for example, GOAMD64=v3, will allow the Go compiler to use AVX2 instructions in the generated binaries (which may improve performance in some cases); but these binaries will not run on older x86 processors that don't support AVX2.
