  -----------
  clang/AMDGPU: Remove driver restriction on --gpu-max-threads-per-block

Previously this flag was only handled for HIP, and would produce an unused
argument warning. There is a custom warning produced by cc1 that the
argument isn't supported, but practically speaking that was unreachable
due to not forwarding the argument. Also add a test for the untested warning.
Also use a simpler method for forwarding the flag to cc1.
