Member predicate Function::getAReturnValueFlowNode

DEPRECATED: bind a Return node explicitly instead, e.g. exists(Return ret | ret.getScope() = this and n.getNode() = ret.getValue()). This API is being phased out together with AstNode.getAFlowNode() to untangle the AST and CFG hierarchies in preparation for migrating the dataflow library off the legacy CFG.

Gets a control flow node for a return value of this function.
