Hm, I dislike relying on type.symbol, but it seems like we can only guarantee getNodeLinks((<PropertyAccessExpression>node).expression).resolvedSymbol exists for Identifier LHSs, since as getTypeOfDottedName recurs, it doesn't set it on other interesting LHS node kinds, like checkPropertyAccessExpressionOrQualifiedName sometimes does.

I initially had an isAnyLike check since I discovered the issue on any, but never and unknown also trigger the issue.
