Just like with AArch64, this is not a reasonable requirement for a new
backend. The tarball contains essentially three different parts:
(1) Generic changes to recogniz TileGX as triple etc.
(2) The target subdirectory.
(3) The clang logic for va_arg etc.

While (1) can be and should be split off, it doesn't change match in
terms of patch size, since the majority will stay in item (2).
