[Driver] Flip the CC1 default of -fdiagnostics-show-option The driver enables -fdiagnostics-show-option by default, so flip the CC1 default to reduce the lengths of common CC1 command lines. This change also makes ParseDiagnosticArgs() consistently enable -fdiagnostics-show-option by default.

// RUN: not %clang_cc1 -Werror -Weverything %s 2> %t
Basic/Diagnostics: Add an isDefaultMappingAsError method, and switch TextDiagnosticPrinter to use that instead of extracting the current mapping via getDiagnosticLevel, which fixes one class of corner cases w.r.t. printing the "-Werror" diagnostic option marker. - The TextDiagnosticPrinter code is still fragile as it is just "reverse engineering" what the diagnostic engine is doing. Not my current priority to fix though. llvm-svn: 140752
