i965/fs: Keep a copy of the live variables class around.
Now optimization passes will be able to look at the per-channel ranges.
v2: Rebase on various optimization pass changes.
v3 (Kenneth Graunke): Rename live_variables to live_intervals; split
introduction of invalidate_live_intervals() into a separate patch.
