Currently, for AMDGPU, when compiling for OpenCL, we unconditionally use `private` as the default address space. This is wrong for cases where the `generic` address space is available, and is corrected via this patch. In general, this AS map abuse is a bad hack and we should re-work it altogether, but at least after this patch we will stop being incorrect for e.g. OpenCL 2.0.
