One question about a fail case, but I think it was pre-existing.

This is just the converse of the previous code, but I think it could happen in certain error cases where the checker falls back to unknownSymbol. Not sure if that’s actually possible in getAliasedSymbol, but I feel like our assumption that symbols always have declarations is a frequent source of crashes, particularly in error-ridden code.
