The directory and file tables now have form-based content descriptors. Parse these and extract the per-directory/file records based on the descriptors. For now we support only DW_FORM_string (inline) for the path names; follow-up work will add support for indirect forms (i.e., DW_FORM_strp, strx<N>, and line_strp).

The input file is hand-coded assembler to generate all the units,
|
|
so we're willing to make exact checks for offsets and such.
