  [Driver,test] Replace CHECK-NOT: warning with -### -Werror

After https://reviews.llvm.org/D156363 changed -### to exist with code 1
if hasErrorOccurred, we can use -Werror to assert no warnings. This is
more reliable than a NOT pattern, which may go stale (when the
diagnostic is updated) without being noticed.
