This patch adds the memory dependence analysis pass to LoopVectorize.

The intent is to introduce patches on top of this one which use it.

I'm not certain at this stage if this is the right thing to use or if
there may be infrastructure available within LoopVectorize that it may
be possible to use without the need to introduce MemoryDependenceAnalysis.
