[llvm] r185040 - SLP: Dont erase instructions during vectorization because it prevents the outerloops from iterating over the instructions.

[Eric Christopher]

So yes on the iterator invalidation? :)

That said, I don't think (I could be wrong) that any other passes
leave RAUW'd instructions around to be cleaned up by subsequent
passes. Is it possible to stick these on a list similar to what you
did with the others to remove after you're done vectorizing the
function?
