Add a DominatorTree argument to isLCSSA so that it doesn't have to
...
compute a set of reachable blocks for itself each time it is called, which
is fairly frequently.

Add Loop contains utility methods for testing whether a loop
...
contains another loop, or an instruction. The loop form is
substantially more efficient on large loops than the typical
code it replaces.

Revert r85667. LoopUnroll currently can't call utility functions which

auto-update the DominatorTree because it doesn't keep the DominatorTree
current while it works.

Merge the enhancements from LoopUnroll's FoldBlockIntoPredecessor into

MergeBlockIntoPredecessor. This makes SimplifyCFG slightly more aggressive,
and makes it unnecessary for LoopUnroll to have its own copy of this code.
