critson added a comment.

- Defer recomputation of live intervals for existing register to after other lowering.
- Add missing recomputation of some source registers which have moved instructions.
- Add missing map insertion for initial exec = S_MOV -1.
- Add missing map insertion for new branch instruction.
- Remove splicing of entire fall through blocks, its impossible to preserve SlotIndexes if we do this.
