<pre>The DWARFDebugLine LineTable parse functionality is decidedly mixed as to its
support for 64-bit line tables. The prologue parser understands DWARF64, and
the prologue's fields are appropriately uint64_t in size. However, the offset
pointer passed around is only a uint32_t one, as are various related variables
e.g. EndOffset and DebugLineOffset in LineTable::parse, which means that you'll
get weird behaviour if we ever actually exercise the parser on a large section.
We should fix this by updating the DataExtractor class to work with uint64_t
sizes, and updating all our offset variables in this file (including the PRIx32
printing of them).</pre>
