Summary: Currently, there is an assertion that prevents us from emitting an AMDGPU global with a non-target specific address space (i.e. numerical attribute). I'm unsure what the original intentions of this assertion were, but we should be able to use OpenCL address spaces when compiling directly to AMDGPU from C++. This is permitted on NVPTX so I'm unsure what this assertion is guarding. The patch simply removes the assertion and adds a test to ensure that these emit the expected address spaces. Fixes https://github.com/llvm/llvm-project/issues/65069
