This is now fully tested. Before this patch errors would be emitted when verifying .debug_names in split DWARF because the DIE offsets wouldn't match up. This patch makes sure that works and only tests .dwo files as .dwp is just another way to access .dwo files. Let me know if there is anything missing. I have more patches needed to allow us to enable .debug_names with split DWARF, but we can't until we can verify the data is good.
