Pavel Labath 2d1fc4375f .debug_names: Parse DW_IDX_die_offset as a reference
Before this patch we were parsing the attributes as section offsets, as
that is what apple_names is doing. However, this is not correct as DWARF
v5 specifies that this attribute should use the Reference form class.

This also updates all the testcases (except the ones that deliberately
pass a different form) to use the correct form class.

Pavel Labath b136c3934e DWARFVerifier: Basic verification of .debug_names
Summary:
This patch adds basic .debug_names verification capabilities to the
DWARF verifier. Right now, it checks that the headers and abbreviation
tables of the individual name indexes can be parsed correctly, it
verifies the buckets table and the cross-checks the CU lists for
consistency. I intend to add further checks in follow-up patches.
