[include-fixer] Make error message sound less like clang crashed.

We suppress all Clang diagnostics (because they would be wrong,
include-fixer does custom recovery) but still want to give some feedback
in case there was a compiler error we couldn't recover from. The most
common case for this is a #include in the file that couldn't be found.
