Basically, the test checks that adding Enum.entries feature doesn't
break the existing code where it clashes with the user-defined "entries"
declaration; it's better to have a black-box test to be sure
that the compiler doesn't invoke something different at runtime
The test covers KT-53153 and KT-56587
