Defining an enum in typeCheckErrors always returns errors

[eejbyfeldt]

Compiler version

3.6.4

Minimized code

import scala.compiletime.testing.typeCheckErrors

object Test {
  def main(args: Array[String]): Unit = {
    println(typeCheckErrors("enum Foo { case A }"))
  }
}

Output

List(Error(object creation impossible, since def ordinal: Int in trait Enum in package scala.reflect is not defined ,enum Foo { case A },11,Typer))

Expectation

The code should not have any type check errors and just print

List()

Works correctly in 3.3.5 and still fails in 3.7.0-RC1
