This patch learn ScalarizerVisitor how to scalarize cases like
load(..., extractelement(...)) and store(..., extractelement(...)) where extractelement returns vector pointer.
We avoid "Inconsistent vector sizes" failure by careful choice of instructions stored in
Scattered and Gathered collections when one of above cases is detected.
