benchstat, cmd/benchstat: group benchmark results

Go 1.9 and up write "pkg", "goos", and "goarch" keys in benchmark
output. benchstat now understands benchmark labels, and uses them to
separate incomparable benchmark results. cmd/benchstat gains a
command-line flag called "-split" to control this, defaulting to
"pkg,goos,goarch".
