Implement basic support for merging function declarations across translation units. llvm-svn: 95794

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

// CHECK: function2.c:3:6: error: external function 'f1' declared with incompatible types in different translation units ('void (Int, double)' vs. 'void (int, float)')

Instead of counting totally diagnostics, split the count into a count of errors and warnings. This allows us to emit something like this: 2 warnings and 1 error generated. instead of: 3 diagnostics generated. This also stops counting 'notes' because they are just follow-on information about the previous diag, not a diagnostic in themselves. llvm-svn: 100675
