Speaking of which, I've been looking into the loop passes and noticed
we do alias analysis and scalar evolution only, trying to clean up the
loop as far as possible.

I suppose that, if we were to define SCCs, split them into groups and
re-arranging into multiple loops, we would still do it in the IR,
right? Would that spoil any other pass? What passes should run
before/after such a pass?

I believe that would be a FunctionPass and registered in the
LoopDependencyAnalysis "runOnLoop()", so it can run when such pass is
called by the PassManager. Or should it be a completely separate pass
(VectorizationPass?) so we can control it from a separate command-line
flag?

cheers,
