[PATCH] D16123: Limit number of blocks scanned for non-local dependences

Ping? As discussed in the associated PR, the algorithmic issues are pretty much unavoidable due to the nature of the analysis. As this fixes a real issue for the 3.8 release, I'd still like to see this go in. For trunk, the work on MemSSA likely makes this whole code obsolete with NewGVN.
