This URL is duplicated 5 times across this file. The idea was to keep it once in common place and put the links on it here. The best place for common description is a declaration of DWARF address space values described in this paper. There is no simple way to reference non-doxygen comment block from other file, so I used phrase `See NVPTXAS::DWARF_AddressSpace` as some kind of pointer to it.
