error stackframes in class constructors have the wrong name

[eps1lon]

Describe the bug

When an error is thrown from a class constructor, the name in the stack frame should read "new NameOfTheClass". SWC is not able to restore these names with sourcemaps. Constructor-less classes will have no mapped name as well. Classes with constructors will use the generic constructor name instead.

Input code

class ReactComponent {
  constructor() {
    throw new Error("Boom");
  }
}

class Component extends ReactComponent {}

new Component();

Config

{
  "$schema": "https://swc.rs/schema.json",
  "jsc": {
    "minify": {
      "mangle": true
    }
  },
  "minify": true,
  "sourceMaps": true,
  "env": {
    "targets": "node >= 20.14.0"
  }
}
