This change seems to have caused test regression. This is Gentoo Linux amd64,
tried LLVM 72d8c2737bb557af9d0c735b9fa30b1b03485627 and 18.1.8.
To reproduce, I've done:
```
cmake -G Ninja "${llvm_project}"/libclc
-DLIBCLC_TARGETS_TO_BUILD="spirv-mesa3d-;spirv64-mesa3d-;r600--;amdgcn--;amdgcn-mesa-mesa3d;amdgcn--amdhsa"
ninja
ninja test
```
The result:
```
