Moved out to separate pass run after SLP vectorizer. Still need to do a test-suite run.
This combines some loads that probably shouldn't be combined. I believe the proper fix here is to split (trunc (shr (load ...), <multiple of 8>), n) in SDAG for targets where the hardware will do load combining. This still exposes the optimization opportunity without regressing anything.
