Fix the behavior of clang's -w flag. It is intended to disable _all_ warnings, even those upgraded to errors via `-Werror=warningname` or `#pragma clang diagnostic error' Fixes: https://llvm.org/PR38231 Differential Revision: https://reviews.llvm.org/D53199 llvm-svn: 352535

// Verify that various combinations of flags properly keep the sign-compare
// warning disabled.
Basic/Diagnostics: Rewrite DiagnosticIDs::getDiagnosticLevel completely to be straighter line code, use the new DiagnosticMappingInfo flags, and eliminate the odd MAP_WARNING_NO_WERROR and friend mappings. - This fixes a host of obscure bugs with regards to how warning mapping options composed with one another, and I believe makes the code substantially easier to read and reason about. llvm-svn: 140770

Prior to adding the new "expected-no-diagnostics" directive to VerifyDiagnosticConsumer, make the necessary adjustment to 580 test-cases which will henceforth require this new directive. llvm-svn: 166280
