41d9f1e039 PR pretty-print/67567 do not pass NULL as a string 
Fortran passes NULL where a non-null string is expected by the pretty-printer,
which causes a sanitizer warning. This could have been found earlier by using
gcc_checking_assert. Even if the assertion is false, the result is just an
incomplete diagnostic, thus it seems more user-friendly to assert only when
checking. I do not have any idea how to properly fix the Fortran bug, thus this
patch simply works-around it.

3563212292 fdiagnostics-color=never does not disable color for some diagnostics 
Actually, I was trying to reject non-warning options as argument to
-Werror=. However, the new test fails because -fdiagnostics-color=never is
always placed by the driver after the warning options when calling the compiler
proper. This patch prunes all -fdiagnostics-color from the command-line but the
last one, which is moved to the first position.
