[SLP]Outline and fix code for finding common insertelement vectors.

Need to outline the code for finding common vectors in insertelement
instructions into a separate function for future patches. It also
improves the process by adding some extra checks for early exit and
fixes a bug where it always finds the match because of erroneous compare
of the same values.
