Mikhael Bogdanov 02d9c526e2 Proper resort variables on inlining lowered ir closures
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..)
