Revert r153516: "Invalidate liveness in Thumb2ITBlockPass."
Revert r153519: "ARMLoadStoreOptimizer invalidates register liveness."
These patches caused miscompilations in povray by turning off branch
folding's updating of live-in lists.
It turns out the the late scheduler depends on the live-in lists, even
if it doesn't need correct kill flags.
