>From what I see in pre-merge check results, some tests fail with this patch. Probably, we should limit the scope of extraData check to specific tags (if the reason of failures is that the checks in this patch apply to tags other than DW_TAG_member, DW_TAG_variable, or DW_TAG_inheritance — the only ones that have MDTuple-in-extraData support implemented).
