[dev.debug] cmd/link: let the linker combine .debug_ranges, remove globals

The linker is pretty good at combining a bunch of symbols into a
section, so let it do .debug_ranges the normal way. Along the way,
remove a bunch of globals that were only used by one function that would
only be called once per invocation.
