Inline accessors should be final

Compiler version

3.1.2

Minimized code

In this example, the inline accessors of B.x generated by f2 override the ones generated by f1 for A.x

class A:
  private var x = 0
  inline def f1(): Int =
    x += 1;
    x

class B extends A:
  private var x = 0
  inline def f2(): Int =
    x += 1
    x

@main def test: Unit =
  val b = new B
  println(b.f1())
  println(b.f2())

Output

1
2

Expectation

Inline accessors should be final to not allow them to be overridden intentionally or accidentally.
