We may not emit bytecode for the evaluation of the to-be-returned expression. In that case we cannot set two return positions for a return statement (one before and one after the expression evaluation). This sets the interpreter apart from full-codegen. Make sure that we always have the second of the two return positions. Note that we end up with separate test cases for ignition and FCG.
