Original problem is that lowered ir closures doesn't meet inliner expectations
about captured variable position in inlining method.
E.g.: Call 'foo(valueParam) { capturedParam }' to
inline function 'foo' with declaration
inline fun foo(valueParam: Foo, inlineParamWithCaptured: Bar.() ->) ....
is reorganized through inlining to equivalent call foo(valueParam, capturedParam1, cp2 ...).
But lowered closure for lambda parameter has totally different parameters order:
fun loweredLambda$x(extensionReceiver, captured1, cp2..., valueParam1, vp2...)
So before inlining lowered closure should be transformed to
fun loweredLambda$x(extensionReceiver, valueParam1, vp2..., captured1, cp2..)

The problem was that anonymous classes wasn't regenerated
although they capture another anonymous class that is a subject
for regeneration
