Ilmir Usmanov eb81c205c7 Replace CHECKCAST kotlin/Unit with ARETURN for tail call optimization
Sometimes instead of {POP, GETSTATIC Unit.INSTANCE, ARETURN} sequence
the codegen emits {CHECKCAST Unit, ARETURN} sequence, which breaks tail
call optimization. By replacing CHECKCAST with ARETURN we eliminate
this issue.
