The TranspBlocks set was used to cache aliasing decision for all processed loads in the parent loop. This is incorrect, because each load can access a different location, which means one load not being modified in a block doesn't translate to another load not being modified in the same block. All loads access the same underlying object, so we could perhaps use a location without size for all loads and retain the cache, but that would mean we loose precision. For now, just drop the cache.
