This has some small speedup: (linking cmd/compile) Dostkcheck 41.0ms ± 1% 38.6ms ± 1% -6.00% (p=0.008 n=5+5) Change-Id: Id62b2fc9e4ef1be92e60e4c03faec0a953eee94e Reviewed-on: https://go-review.googlesource.com/c/go/+/222303 Run-TryBot: Cherry Zhang <cherryyz@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Than McIntosh <thanm@google.com>
