Issue:
SWC `compress` removes string literal’s `.toUpperCase()` and produces incorrect code
### Describe the bug

The attached playground shows a stripped-down version of a code file that appears in my next.js project.

The SWC minifier/“compressor” removes `.toUpperCase()` from a string literal without uppercasing the string literal. The result is incorrect output.

### Input code

```typescript
export class Renderer {
  renderStaticFrame(string1, string2) {
    const line1Text = `${string1} and ${string2}`.toUpperCase();
    const line2Text = 'line 2 text'.toUpperCase();

    const text = `${line1Text}\n${line2Text}`;
    return text;
  }
}

console.log(new Renderer().renderStaticFrame('a', 'b'));
```

### Output code

```js
export class Renderer {
  renderStaticFrame(string1, string2) {
      let line1Text = `${string1} and ${string2}`.toUpperCase();
      return `${line1Text}\nline 2 text`;
  }
}
console.log(new Renderer().renderStaticFrame('a', 'b'));
```

### Expected behavior
Both lines are uppercase.
```diff
❯ node swc-input.js   
A AND B
LINE 2 TEXT
```

### Actual behavior
The second line is printed in lowercase, because the `toUpperCase` function was removed in the SWC output.
```diff
❯ node swc-output.js     
A AND B
line 2 text
```
