Update VerifyDiagnosticConsumer to only get directives during parsing. The old behavior was to re-scan any files (like modules) where we may have directives but won't actually be parsing during the -verify invocation. Now, we keep the old behavior in Debug builds as a sanity check (though modules are a known entity), and expect all legitimate directives to come from comments seen by the preprocessor. This also affects the ARC migration tool, which captures diagnostics in order to filter some out. This change adds an explicit cleanup to CaptureDiagnosticsConsumer in order to let its sub-consumer handle the real end of diagnostics. This was originally split into four patches, but the tests do not run cleanly without all four, so I've combined them into one commit. Patches by Andy Gibbs, with slight modifications from me. llvm-svn: 161650

Change VerifyDiagnosticConsumer so that it *must* contain at least one "expected-*" directive. As a result, for test-cases that are not expected to generate any diagnostics, an additional directive "expected-no-diagnostics" has been implemented which can then be included in such test-cases. This new directive may not be used in conjunction with any other "expected-*" directive. This change was initially proposed as a solution to the problem highlighted by check-in r164677, i.e. that -verify will not cause a test-case failure where the compile command does not actually reference the file. Patch reviewed by David Blaikie. llvm-svn: 166281
