Simon Pilgrim ae1f013495 [X86][SSE] Add PACKUS support to combineVectorTruncation 
Similar to the existing code to lower to PACKSS, we can use PACKUS if the input vector's leading zero bits extend all the way to the packed/truncated value.

We have to account for pre-SSE41 targets not supporting PACKUSDW
