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.

if it can be implemented in 3 or fewer discrete altivec instructions, codegen
it as such.  This implements Regression/CodeGen/PowerPC/vec_perf_shuffle.ll

address has to be 16-byte aligned but the values aren't spilled to 128-bit

one type (v4i32) so that we don't have to write patterns for each type, and
so that more CSE opportunities are exposed.
