A change just landed to unify some of the tests you can see that change here: 
https://github.com/llvm/llvm-project/commit/e99aa4a500b0f271b327432d404a9c1f72c6850a
essentially you want to define a `TARGET` so you don't have to have one line 
for `dx` and one line for `spv` intrinsics.
example:
```
%hlsl. sign = call half @llvm.[[TARGET]]. sign.f16(
```
