[dev.link] cmd/link: parallelize asmb on amd64 Introduces a parallel OutBuf implementation, and POC on amd64. Due to some of the weird behaviors I saw on MacOS (SIGBUS while calling msync), I will wait for feedback to port to other architectures. On my mac, sped up Asmb by ~78% for cmd/compile (below). Will likely have an appreciable speedup on kubelet benchmark. Asmb 39.1ms ±11% 8.5ms ±10% -78.17% (p=0.000 n=10+9) TotalTime 596ms ± 2% 577ms ± 8% -3.07% (p=0.034 n=8+10) Change-Id: Id2a2577c3f4da155d8dccc862897f43b941877ac Reviewed-on: https://go-review.googlesource.com/c/go/+/223742 Run-TryBot: Jeremy Faller <jeremy@golang.org> Reviewed-by: Cherry Zhang <cherryyz@google.com> Reviewed-by: Than McIntosh <thanm@google.com>
