This cuts 6 seconds off all.bash with the new go command. Not a ton, but also an easy 6 seconds to grab. The -tags=use_go_run in the misc/cgo tests is just some go command flag that will make run.go use go run, but without making everything look stale. (Those tests have relative imports, so go tool compile+link is not enough.)
