Original issue: https://github.com/rust-lang/rust/issues/21195 Relevant PR: https://github.com/rust-lang/rust/pull/30778 Prior to this commit, if a compiletest testcase included the text "HELP:" or "NOTE:" (note the colons), then it would indicate to the compiletest suite that we should verify "help" and "note" expected messages. This commit updates this check to also check "HELP" and "NOTE" (not the absense of colons) so that we always verify "help" and "note" expected messages.
