Define class property in expression level macro

[Ziaw]

  public macro Macro1()
  {
      Test.test(ImplicitCTX());
      <[]>
  }

  module Test
  {
    public test(t: Typer): void
    {
        t.CurrentTypeBuilder.Define(
            <[decl: Prop : int { get {1} } ]>
        );
    }
  }

throws ICE on usage

But defining field or method works properly.
