This switches most error printing to use diagnostics instead of direct stream writes, even when not a specific file diagnostic. I'm allowing empty filenames for this use-case. This allows a little more specific testing to validate coverage of output using the diagnostic coverage test. I'm adding a few tests to cover things that weren't previously tested. Separately, this also forces a little more standardization in format... considering how changes like #4568 show effort being spent to _mirror_ diagnostic style, my thought is now to just use diagnostic code where possible. Note this also allows incrementally better testing of the language server; I'm changing the crash fix from #4847 in favor of diagnostic testing. --------- Co-authored-by: Chandler Carruth <chandlerc@gmail.com>
