[amdgcn] Add hook for DWARF address spaces.
Map GCN address spaces to the proposed DWARF address spaces defined by AMD at
https://llvm.org/docs/AMDGPUUsage.html#amdgpu-dwarf-address-class-mapping-table
gcc/
* config/gcn/gcn.c: Include dwarf2.h.
(gcn_addr_space_debug): New function.
(TARGET_ADDR_SPACE_DEBUG): New hook.
