Bunch of changes were necessary: - refactor attaching the frame states/lazy bailouts in AstGraphBuilder (essentialy reland of r23096), - attaching frame state to some JS nodes in a similar way to attaching context (this is quite ugly and we should take another look at this), - new bailout point for the debugger statement, - register allocation constraints for the frame states, - generating translations and deopt entries, attaching them to safepoints, - enabled one mjsunit test for debugger state that uses the generated frame state.
