Should probably have the values for flat and region

This is for OpenCL kernel argument reflection. flat and region address spaces do not show up in kernel arguments.

Region would if that extension were ever finished. There's no real reason we can't support flat either. The values should be there to make sure they are reserved / keep the same values as the address space enum
