i965/vs: Improve live interval calculation.

This is derived from the FS visitor code for the same, but tracks each channel
separately (otherwise, some typical fill-a-channel-at-a-time patterns would
produce excessive live intervals across loops and cause spilling).

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=48375
          (crash -> failure, can turn into pass by forcing unrolling still)
