Change the run.go driver to recognize the "gc" build tag. Change existing tests to use the "gc" build tag if they use some feature that seems specific to the gc compiler, such as passing specific options to or expecting specific behavior from "go tool compile". Change tests to use the "!gccgo" build tag if they use "go build" or "go run", as while those might work with compilers other than gc, they won't work with the way that gccgo runs its testsuite (which happens independently of the go command).
