The assignment `sink, *(&ok) = y.(int)` should (and does) escape a value to the heap, but this detail is missed because the implicit conversion of the multi-value expression `y.(int)` isn't visible to escape analysis (because it's not inserted until desugaring during walk). For Unified IR, I plan to apply this desugaring earlier (because it's necessary for correct dictionary handling), which means we'll now (correctly) report the heap escape. Due to limitations of the $GOROOT/test harness, the easiest way to handle that GOEXPERIMENT=unified gets this right while GOEXPERIMENT=nounified does not is to split the test case into separate files. Hence this CL.
