the tan llvm inttrinsic was defined in `isTriviallyVectorizable` https://github.com/llvm/llvm-project/blob/8ab66775dc885f7a99ee5f53771ce555e42085f9/llvm/lib/Analysis/VectorUtils.cpp#L71. 

This change is just linking the tan libfuncs to the intrinsic so the libfuncs can also be vectorized. As written there is no  backend specific behavior. It is going to vectorize tan across all backends. So I don't know how the test case you have asked for make sense.
