The precommit CI failures seem unrelated to these changes.

+union { char x[]; } r = {0}; // expected-error {{flexible array member 'x' in a union is not allowed}}
----------------
I think we might want to move this to its own test file so we can test the various edge cases. I'd like to see a RUN line that tests explicitly in `-fms-compatibility` mode to demonstrate that we do not issue this diagnostic, and RUN lines for C++ mode as well.
