errors with promotion and non-nilable owned

[mppf]

I would expect both of the following programs to function but the result in errors after PR #14835. They produce different errors.

class C {
  var x: int;
}
  
record R {
  var x;
  proc init() {
    x = new owned C(1..10);
  }
}

proc main() {
  var r = new R();
  writeln(r);
}

class C {
  var x: int;
}

record R {
  var x: [1..10] owned C;
  proc init() {
    x = new owned C(1..10);
  }
}

proc main() {
  var r = new R();
  writeln(r);
}

When this issue is resolved, workaround changes to test/studies/shootout/chameneos-redux/elliot/chameneosredux-ejr.chpl should be removed.

The second example compiles and runs for me with #14835, at least as of 0a7f2d4

Both examples compile and run for me, and are clean under --memLeaks.
