[llvm] [CodeGen] Fixed vector halving bug for masked load
Summary:
Given a VL=14 that is enveloped by a proper VL=16, splitting the
masked load using the enveloping halving VL=8/8 should yields
should eventually yield V=8/5. This fixes various assert failures
in getHalfNumVectorElementsVT() and IncrementMemoryAddress().
Note, I suspect similar fixes will be needed for other masked
operations, but for now I send out a fix for masked load only.
