misched: Added handleMove support for updating all kill flags, not just for allocatable regs.
...
This is a medium term workaround until we have a more robust solution
in the form of a register liveness utility for postRA passes.

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.
