member functions.
(read_context::load_debug_info): Painfully Get a handle on the
alternate debug info section too. We shouldn't have to do all
this work; we could use the new dwarf_getalt() function from
libdw, but we cannot as we want to support supports that predate
that api. When a version of elfutils gets released with that api
though, we should conditionally use that instead.

the DIE is from alternate debug info or not, and act upon that.
(build_die_parent_maps): Renamed build_die_parent_map into this
and make it build DIE -> parent DIE relationship for the alternate
debug info file as well.
(find_last_import_unit_point_before_die, ): Adjust to use the
information about if the relevant DIEs are in alternate debug info
or not.

decl map, that is per TU just as the primary DIE -> decl map.
Adjust to use the information about if the relevant DIEs are in
alternate debug info or not.

maps (one for the primary debug info and one for the alternate
