Today, if run.go doesn't understand a test header line it just ignores the test, making it too easy to write or edit tests that are not actually being run. - expand errorcheck to accept flags, so that bounds.go and escape*.go can run. - create a whitelist of skippable tests in run.go; skipping others is an error. - mark all skipped tests at top of file. Update #4139. R=golang-dev, bradfitz CC=golang-dev https://golang.org/cl/6549054
