Daniel Dunbar aa11138543 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.
