Clang diagnostics should not start with a capital letter or use trailing punctuation (https://clang.llvm.org/docs/InternalsManual.html#the-format-string), but quite a few driver diagnostics were not following this advice. This corrects the grammar and punctuation to improve consistency, but does not change the circumstances under which the diagnostics are produced.
