There are no formal selection criteria here I think. The test aims to cover
the different functional aspects of `-fdeclare-opencl-builtins`. The new
functional aspect for `-fdeclare-opencl-builtins` in this patch is an extension
that is not in `OpenCLExtensions.def`, so it makes sense to add such a case to
the test.
I will add a comment to the top of the test file.
