Huáng JùnliàngandGitHub 26af3161e6 Optimize do expression output (#17444)
* add new test case

* opt: conditionally apply the flatten transform

Only apply the flatten transform when the do expression contains Break/Continue/Return. This enables us to optimize the output since we don't have to memoize intermediate results.

* update test outputs

* remove unreachable code

variable declaration within for in/of can not have initializer.

* update test case to cover spread element

* add more test cases for early exit scenario

* make node 6 happy

* revert complex variable declaration removal
