Eli Friedman 21d28d5c67 Preserve domtree and loop-simplify for runtime unrolling. ...

Mostly straightforward changes; we just didn't do the computation before.
One sort of interesting change in LoopUnroll.cpp: we weren't handling
dominance for children of the loop latch correctly, but
foldBlockIntoPredecessor hid the problem for complete unrolling.

Currently punting on loop peeling; made some minor changes to isolate
that problem to LoopUnrollPeel.cpp.

Adds a flag -unroll-verify-domtree; it verifies the domtree immediately
after we finish updating it. This is on by default for +Asserts builds.
