[Mesa-dev] [PATCH 2/2] i965/sf_state: Pull flat_enables out of prog_data

Previously, we were walking over the shader source to figure out which
inputs should be marked flat. Now, we can just pull it out of prog_data.
This is needed for properly setting up 3DSTATE_SF/SBE for Vulkan and it
also means that it will get properly cached.
