New interface function is added to VectorUtils
Value *getSplatValue(Value *Val);
It complements the CreateVectorSplat(), which creates 2 instructions - insertelement and shuffle with all-zero mask.
The new function recognizes the pattern - insertelement+shuffle and returns the splat value (or nullptr).
It also returns a splat value form ConstantDataVector, for completeness.
