PR #141106 changed the debuginfo metdata to allow dynamic bit offsets and sizes. This caused a crash in lld when using LTO. The problem is that lazyLoadOneMetadata assumes that the metadata in question can be cast to MDNode; but in the typical case where the offset is a constant, this is not true. This patch changes this spot to allow non-MDNodes through. The included test case comes from the report in #141106.
