[PATCH] D19694: [LV] Only bail on interleaved accesses in predicated blocks

With this revision, we collect all accesses in the loop, even those in the predicated blocks, so we can account for any dependences (http://reviews.llvm.org/D19984). We prevent forming interleaved groups with predicated accesses unless the accesses are in the same block. I've also added Silviu's code example as a new test case.
