A region identifies a set of vector instructions generated by vectorization passes. The vectorizer can then run a series of RegionPasses on the region, evaluate the cost, and commit/reject the transforms on a region-by-region basis, instead of an entire basic block. This is heavily based ov @vporpo's prototype. In particular, the doc comment for the Region class is all his. The rest of this commit is mostly boilerplate around a SetVector: getters, iterators, and some debug helpers.
