DWARF 5 standardized the .gnu_debugaltlink section that dwz emits in multi-file mode. This is handled via some new forms, and a new .debug_sup section. This patch adds support for this to gdb. It is largely straightforward, I think, though one oddity is that I chose not to have this code search the system build-id directories for the supplementary file. My feeling was that, while it makes sense for a distro to unify the build-id concept with the hash stored in the .debug_sup section, there's no intrinsic need to do so. This in turn means that a few tests -- for example those that test the index cache -- will not work in this mode.
