Use dominance frontier to fixup incoming edges of successor blocks not domianted by DeadBB.
Use df_iterator to walk and delete basic blocks dominated by DeadBB.

- If the defs of a spilled rematerializable MI are dead after the spill store is deleted, delete
  the def MI as well.

Fix for PR1596: AdjustCopiesBackFrom() should conservatively check if any of its sub-registers may overlap with the interval of the copy that's being coalesced.

If a MI's def is remat as well as spilled, and the store is later deemed dead, mark the def operand as isDead.

no more uses within the MBB and the spilled value isn't live out of the MBB.
Then it's safe to delete the spill store.

Re-implement trivial rematerialization. This allows def MIs whose live intervals that are coalesced to be rematerialized.
