x/build: add amd64 AMD "D" performance builders

[matloob]

CC @golang/runtime @golang/release

I'm proposing setting up new performance builders for amd64 AMD chips. We have the C216 and C388 builders for Intel chips.

We could add two amd builders to match that? Maybe starting with a C4D builder?
