05843dc6ab97a00cbde7aa4f08bf3692eb83109d changed the serialization of the body of LambdaExpr to avoid a mutation in LambdaExpr::getBody and to avoid a missing body in LambdaExpr::children. Unfortunately this replaced one bug by another: we are now duplicating the body during deserialization; that is after deserialization the identity: E->getBody() == E->getCallOperator()->getBody() does not hold. Fix that by instead lazily loading the body from the call operator when needed. Differential Revision: https://reviews.llvm.org/D83009 Reviewed By: martong, aaron.ballman, vabridgers
