4a998b9ca8 Pull some code out into a helper function.
Effeciently codegen even splats in the range [-32,30].

This allows us to codegen <30,30,30,30> as:

        vspltisw v0, 15
        vadduwm v2, v0, v0

instead of as a cp load.

it as such.  This implements Regression/CodeGen/PowerPC/vec_perf_shuffle.ll
