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

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

Merge the enhancements from LoopUnroll's FoldBlockIntoPredecessor into

MergeBlockIntoPredecessor. This makes SimplifyCFG slightly more aggressive,
