IWYU: Suppress warnings from the internal Clang

Browse Source 
Do not obscure IWYU's report with warnings from its internal Clang.
We have other testing for such warnings.  Also, when compiling with
a non-Clang compiler we might use warning options that IWYU's Clang
does not understand, and we don't want to see warnings about that.
