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.
