returning Unit. Because on resume the result might be not a Unit if
the callee is tail-call and its callee return something different from
Unit and suspends.
Luckily, we generated ReturnsUnitMarker on such calls in all release
versions since 1.3. So, even if the code is inline and generated by
older versions, it will still work correctly.
The only version of the compiler, which does not generate the markers,
is 1.3.60-eap-76, because we did not generate the markers since
cc06798e2c. But I think, this is not
an issue.
