[PATCH] D53596: [ThinLTO] Fix a crash in lazy loading of Metadata

[Steven Wu via Phabricator via llvm-commits]

My thought is that this patch should make bitcode reader more robust when lazy loading, which is always a good thing. If this is a performance regression, the regression is coming from how debug information is generated. If there are no such forward-ref in the metadata, there is no slowdown with this patch. We can investigate performance regression post commit if needed.
