These are new debug types that ships with the latest Windows SDK and would warn and finally fail lld-link. The symbols seems to be related to Microsoft's XFG which is their version of CFG. We can't handle any of this yet, so for now we can just ignore these types so that lld doesn't fail with a new version of Windows SDK.
