[PATCH] D100501: [cland] Dont emit missing newline warnings when building preamble

That's a good point. But PP doesn't know if there's trailing content or not (in clangd's case).
So we'll end up not showing the diag even when we should (i.e. whole file is preamble without a new line at eof). 
It doesn't sound too bad, but it'll effect all tools building preambles (including clang) and not just clangd so I am a little hesitant.
