'while' and 'do-while' loop generator fixes.

Generate 'do-while' loop body as IrComposite, because variables declared
in loop body should be visible in loop condition.
Wrap 'do-while' loop in IrBlock so that variables declared in loop body
are not visible outside of the loop.

Generate 'while' and 'do-while' loops as expressions of type Unit.
