This patch updates X86InstCombineIntrinsic.cpp to use the newly updated CreateShuffleVector.

The tests are updated because the updated CreateShuffleVector uses poison value for the second vector.
If I didn't miss something, the masks in the tests are choosing elements from the first vector only; therefore the tests are having equivalent behavior.
