Title: WIP: Enable using memory sanitizer with Julia

Memory sanitizer is a Valgrind like tool, but about 10x faster and uses compiler techniques rather than dynamic execution. You'll need this patch to LLVM https://gist.github.com/loladiro/8748036. I basically put this here in case anyone wants to play with it, because I might not get to it in a while.
