Thanks, LGTM

Sorry about the delay - we got sidetracked into some ideas about whether these 
errors should actually be surfaced to the user as diagnostics instead. But that 
shouldn't block this patch.



================
Comment at: clang-tools-extra/clangd/ParsedAST.cpp:296
+    elog("Failed to prepare a compiler instance: {0}",
+         ASTDiags.getNumErrors()
+             ? static_cast<DiagBase &>(ASTDiags.take().back()).Message
----------------
there's a bunch of logic that determines which diags we actually end up storing.

I'd suggest always calling take() and testing whether the result is empty, 
rather than using getNumErrors() which bypasses all our logic.

Luckily, we do (always?) end up storing the relevant diags here, assuming 
they're errors without a source location attached.
However I don't think we should hard-code that assumption here.
