i965/fs: Invalidate live intervals when compacting; don't fix them.
When compacting the list of VGRFs, we patch up the live interval ranges
(which are indexed by VGRF number). Unfortunately, once we make
per-component data available, this will become too complicated to
maintain. Instead, simply invalidate them.
This was pulled out of a patch by Eric Anholt.
