### Changes
1. The left-hand of `AssignmentExpression` is always `ReferenceFlags::Write`
```js
let a = 0;
console.log(a = 0);
^ Write only
```
2. The `argument` of `UpdateExpression` is always `ReferenceFlags::Read | Write`
```js
let a = 0;
a++;
^ Read and Write
```
This change might cause some trouble for `Minfier` to remove this code, because ‘a’ is not used elsewhere. I have taken a look at `esbuild` and `Terser`. Only the `Terser` can remove this code.

fix(transformer/async-to-generator): incorrect transform when super expression is inside async method ( #7171 )
...
After transformation, super expressions have moved to unexpected places. This PR replaces super expression to call expression, and then inserts the super methods to the top of the method body.
For example:
Before:
```js
class G {
async method() {
super.foo()
}
}
```
After:
```js
class G {
method() {
var _superprop_getFoo = () => super.foo,
_this = this;
return _asyncToGenerator(function* () {
_superprop_getFoo().call(_this);
})();
}
}```

test(transformer): transform checker output symbol name for mismatches ( #6286 )
...
Transform checker include symbol names in output for symbol mismatches. This is rather more helpful for locating bugs than just `SymbolId(3)`.
