Simplify scalar GEPs into Private vectors into vector extract/insert - #1703

Conversation
Add SimplifyPointerBitcastPass::runOnGEPToVector to rewrite scalar loads and stores through a Private GEP into a vector (<= 4 elements, e.g. from ((type*)&vec)[idx] after DestructurizeGEPPass and runOnImplicitGEP) into vector load + extractelement / insertelement + vector store, and run SROA after SimplifyPointerBitcastPass so that the underlying vector alloca is promoted to registers just like vec[idx].
