As is the case with [the original implementation from ARM.cpp](https://github.com/llvm/llvm-project/blob/8d7823ea8f40cf5df1c623018bf9c0a308fa4a36/clang/lib/CodeGen/TargetBuiltins/ARM.cpp?plain=1#L1118-L1175), I would expect all intrinsics implemented in this method to lower directly via `emitNeonCall`. Why diverge?
