[CostModel][X86] getShuffleCost - shuffles with only one defined element are always cheap (#124412) ...

If we're just moving a single element around inside a 128-bit lane (probably as an alternative to extracting it), we can assume this is cheap as a single PSRLDQ/PSHUFD/SHUFPS.

I've got the horrid feeling we're moving towards matching all SSE shuffle patterns inside the cost model, but I'm going to do my best to avoid this for now :|
