simpleregistercoalescing -> regcoalescing. It's too long for me to handle.

Don't assume that only Uses can be kills. Defs are marked as kills initially
...
when there are no uses. This fixes a dangling-pointer bug, where pointers to
deleted instructions were not removed from kills lists. More info here:

Factor live variable analysis so it does not do register coalescing
...
simultaneously. Move that pass to SimpleRegisterCoalescing.
This makes it easier to implement alternative register allocation and
coalescing strategies while maintaining reuse of the existing live
interval analysis.
