refactor(es/minifier): Remove mutated and mutation_by_call_count (#7890) 
**Description:**

`mutated` can be seen as a combination of `reassigned` and `has_property_mutation`, and `mutation_by_call_count` is simply useless.

fix(es/minifier): Abort seq inliner if var is not fn_local or reassigned (#7804) 
**Description:**

It turns out that the original implementation of `infect`is incomplete
because it cannot cover function param, and the new implementation
introduced in #7772 is redundant because what
[terser](https://github.com/terser/terser/blob/master/lib/compress/tighten-body.js#L909C18-L909C28)
do is basically checking `fn_local`

fix(es/minifier): Abort seq inliner if a same var is defined in outer scope (#7772)

fix(es/minifier): Mark all function params as potential property mutation (#7409) 
**Description:**

This issue is more severe than I originally thought. It raises not in
array indexing, but in function calls and property mutation. We should
treat all function arguments as potentially be property mutated,
otherwise following example

```js
class A {
	a = 1

	toString() {
		return this.a
	}
}

const a = new A()

function foo(x) {
	x.a++
}

const b = a + 1

foo(a)

console.log(b)
```

would be error(It should log 2, but logs 3 after compress).

As the result, massive regressions is unavoidable, since some of these
optimizations may indeed cause error. Part of them can be mitigated with
following optimization -- allow inline of ident even if its original
value is mutated. Consider

```js
export function foo(x) {
   const y = x
   x.a = 1
   y.b = 2
}
```

If x is a primitive value, all mutations to its properties are ignored;
if x is a object, then y refers to the same object no matter what
mutation is performed.

And there's still room for more, currently following code
```js
export function foo(x) {
    const y = Math.floor(x);
    g(y);
}
```
But I'd rather do it in a separate PR.


**Related issue:**

 - Closes #7402.
