Not in the frontend or psi2ir, though, so this not a complete
implementation of KT-1436, but rather a part of it that is currently
useful to make other code compile. In particular, lambdas passed to
array constructors and JVM-style `assert` are inlined as IR returnable
blocks, which are then converted into `do { ... } while (false)` loops,
so non-local returns from them become non-local `break`s.
