[PATCH] D30680: new method TargetTransformInfo::supportsVectorElementLoadStore() for LoopVectorizer

Sorry about the delay on this but I was working on something related for ARM that may benefit from this as well.  What I need for ARM is something that can communicate to the SLPVectorizer that load-pair and store-pair (of two registers) is efficiently supported on the target.  I am wondering if we can combine the two things if your new hook would take the type and the vectorization width.

What do you think?
