There will be following changes: 1. LoopHeader IR will have more than two input 2. Add DepenedRelay for DeoptCheck 3. Refactor dead region elimination for 'BytecodeCircuitBuilder' 4. Fix live range analysis bug for try catch 5. Refactor gate generating for 'phi' 'merge' 'loopexit' and genenator gates 6. Refactor frameState generating, all merge(LoopExit) and side-effect gate will have frameState 7. Refactor loopAnalysis for 'BytecodeCircuitBuilder' 8. Add GetLoopInfo for GraphLinearizer's 'GateRegion' 9. Fix a LoopAnalysis bug 10. Fix a TypeInfer bug for infer namespace object 11. Remove dead StateSplit in state split linearizer pass Issue: https://gitee.com/openharmony/arkcompiler_ets_runtime/issues/I88W5H Signed-off-by: sunzhe23 <sunzhe23@huawei.com>
