<pre>Done. It's nothing like the patch from Ville because we recently completely
rewrote the way you shove that sort of side-band data into the shader. It's
actually way easier now.

anv: Emulate texture swizzle in the shader when needed
Now that we have the descriptor buffer mechanism, emulated texture
swizzle can be implemented in a very non-invasive way. Previous
attempts all tried to extend the push constant based image param
mechanism which was gross. This could, in theory, be done much faster
with a magic back-end instruction which does indirect MOVs but Vulkan on
IVB is already so slow this isn't going to matter much.
