Support secondary constructors in JVM backend

There is a lot of changes about closures calculating and generating.

1. As classes can have more than one constructor each of them should
have closure arguments.

2. Captured variables set is the same for all of them.

3. Within constructors bodies/delegating calls closure parameters
should be accessed through method arguments because fields may be
not initialized yet.
