This is the pass we have locally that does loop idiom recognition specifically for Hexagon.

The problem with it is how it's hooked up with the rest of LLVM (pass manager in particular).  Ideally, we'd have an insertion point here where each target could add their own passes.  We'd also need to have the target triple available in the PassManagerBuider to determine what the actual target is.
