c4118452bc Remove the -live-regunits command line option. 
Register allocators depend on it being permanently enabled now.

7824152557 Only update regunit live ranges that have been precomputed. 
Regunit live ranges are computed on demand, so when mi-sched calls
handleMove, some regunits may not have live ranges yet.

That makes updating them easier: Just skip the non-existing ranges. They
will be computed correctly from the rescheduled machine code when they
are needed.
