fix: async arrow functions should not be allowed after binary… (#11284)
* Forbid async arrow functions after binary operator.

This commit makes Babel throw an error when parsing
code like "3 + async() => 2".

* Make atPossibleAsync more accurate

* Change atPossibleAsync to atPossibleAsyncArrow

Add an extra test to atPossibleAsync and refactor it to
atPossibleAsyncArrow. This also fixes a bug in the Typescript plugin,
so a new test has been added.

* Add test for async arrow after unary operator

9bc04baeb5 fix(babel-parser): avoid state.clone() to clone the whole token store (#11029)
* fix(babel-parser): avoid state.clone() to clone the whole token store

Fixed the performance issue on large input when turned on option {tokens: true} and typescript plugin which uses quite a few state.clone().

* test(babel-parser): turn on 2 typescript tests with tokens:true

The output.json is generated by old master to make sure no regression.

* fix(babel-parser): avoid duplicated tokens trapped by mainly typescript/flow plugins

* test(babel-parser): update output.json to latest master result

* chore(babel-parser): improve performance by storing tokensLength in state
