Alexis Laferrière 9d090c8aab Serialization: Recover from errors under loadObjCMethods ...

The diagnostics about unintended override of Objective-C methods
deserializes more decls than strictly necessary. Any of these could
trigger a deserialization failure if they rely on missing dependencies.
Simply ignore methods failing to deserialize instead of crashing.

We could do better here as this logic may ignore methods that are actually
colliding. Instead we could put more information in the lookup table to
avoid the need for fully deserializing the decl.
