Philip Reames 7d6e8f2a96 [slp] Delete dead scalar instructions feeding vectorized instructions 
If we vectorize a e.g. store, we leave around a bunch of getelementptrs for the individual scalar stores which we removed. We can go ahead and delete them as well.

This is purely for test output quality and readability. It should have no effect in any sane pipeline.
