[PATCH] D81766: [VectorCombine] try to create vector loads from scalar loads

Patch updated:
Adjusted to match the most basic pattern that starts with an insertelement (so there's no extract created here). Hopefully, that removes any concern about interactions with other passes. Ie, the transform should almost always be profitable. (We could make an argument that this could be part of canonicalization, but we conservatively try not to create vector ops from scalar ops in passes like instcombine.)
