Could you take a look, please?
Description:
Initial support for debugger frame state in Turbofan.
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.
