i965: Store the command parser version number in intel_screen
In order to detect whether the predicate source registers can be used in a later patch we will need to know the version number for the command parser. This patch just adds a member to intel_screen and does an ioctl to get the version. Reviewed-by: Kenneth Graunke <[email protected]>
