nicholas added a parent revision: D60752: [NFCI] Use less memory by storing the Loop* as visited instead of storing each BasicBlock* in the block as visited..

The new implementations are one "fast path" implementation using the DominatorTree and not supporting ExcludedBlocks, and a "slow path" that walks BasicBlocks and supports ExcludedBlocks. Both take advantage of LoopInfo if available.
