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.
This is a hack to work around the fact that type mappings should not be
inherited by inlining contexts for lambdas called from anonymous
objects. As the lambda can call the inline function again, this could
produce a reference to the original object, which is remapped to a new
type in the parent context. Unfortunately, there are many redundant
`MethodRemapper`s between the lambda and the class file, so simply
editing `TypeRemapper` does not work. Hence, this hack. For now.
(Issue found by compiling IntelliJ IDEA BTW.)
