Decorators for symbol property are compiled incorrectly

[dko-slapdash]

Describe the bug

When using a @decorator for a symbol property, the compiler generates a wrong output.

Input code

const sym = Symbol("sym");

class Cls {
  @Memoize()
  [sym]() {}
}

Config

{
  "jsc": {
    "parser": {
      "syntax": "typescript",
      "decorators": true
    },
    "target": "es2020"
  },
  "module": {
    "type": "commonjs"
  }
}

Expected behavior

It should define _key before defining the class.

Actual behavior

_key is undefined, so the property does not define. Compiled result:

...
const sym = Symbol("sym");
var _key;
class Cls {
    [_key]() {}
}
_key = sym; // <--- This must be BEFORE the class definition
__decorate([
    Memoize()
], Cls.prototype, _key, null);
