i965: Split out per-stage dirty-bit checking into separate functions

The dirty-bit checking from each brw_upload_<stage>_prog function is
split out into its a new brw_<stage>_state_dirty function.

This commit is intended to have no functional change. It exists in
preparation for some upcoming code movement in preparation for the
shader cache.
