||aranges does not have debug info length
Section 6.1.2, pg 121
Currently the .debug_aranges section header contains debug_info_offset.
However, it does not have a debug_info_length field. Other "index"
sections, such as .debug_pubnames, do have this field.
The lack of this field means that it is not possible to determine
whether a CU is missing aranges information simply by scanning .debug_aranges.
Instead the reader must also scan .debug_info to construct the list
Deferred, pending possible changes to lookup tables.
