i965: Fix SNB GPU hangs when a blorp batch is the first thing to execute.
The GPU apparently goes looking for constants even though there are no shader stages enabled, and gets stuck because we haven't told it there are no constants to collect. If any other user of the 3D pipeline had run (even the Render accel of the X server!) since power on, then the in-GPU constant buffers would have been set up with some contents we didn't use, and we would succeed. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=56416 Reviewed-by: Kenneth Graunke <[email protected]> Tested-by: Dave Airlie <[email protected]> NOTE: This is a candidate for the stable branches.
