OpenCL kernel failing to compile on Clover #2800
Description
I have an AMD Radeon running on Fedora 31, its device signature is:
Clover: Radeon RX 580 Series (POLARIS10, DRM 3.36.0, 5.5.8-200.fc31.x86_64, LLVM 9.0.0), 8192 MB
However running a number of examples like "surface_opencl" (master branch as of now) produces this kind of error:
ArrayFire v3.8.0 (OpenCL, 64-bit Linux, build bc37e8a)
[0] Clover: Radeon RX 580 Series (POLARIS10, DRM 3.36.0, 5.5.8-200.fc31.x86_64, LLVM 9.0.0), 8192 MB

This seems to be related to this compiler argument "-D dim=0" and that lne in a OpenCL include file for example:
_CLC_DECL size_t get_global_size(uint dim);
It is clear that it should yield a compile error. Maybe ArrayFire should use better mangled macro name like "af_dim_opencl" or something else... ?
Best regards.
