Subject: [PATCH] i965: Clean up fs_visitor::run and rename to run_fs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that fs_visitor::run is back to being only fragment
shader compilation, we can clean up a few stage == MESA_SHADER_FRAGMENT
conditions and rename it to run_fs.
