The methods above the frame that rethrows aren't included in the frames
constructed from an exception object: new System.Diagnostics.StackTrace(e)

This bug prevents IronRuby to display correct stack traces.

Reproducible: Always

Steps to Reproduce:
Compile and run the following code:

using System;
using System.Runtime.CompilerServices;


public class C {

    public static void Main() {
        Baz();
    }

    [MethodImpl(MethodImplOptions.NoInlining)]
    public static void Baz() {
        try {
            Bar();
        } catch(Exception e) {
            Console.WriteLine(new System.Diagnostics.StackTrace(e));
        }
    }

    [MethodImpl(MethodImplOptions.NoInlining)]
    public static void Bar() {
        try {
          Foo();
        } catch {
          throw;
        }
    }

    [MethodImpl(MethodImplOptions.NoInlining)]
    public static void Foo() {
        throw new Exception();
    }

}
Actual Results:  
   at C.Foo()
   at C.Bar()

Expected Results:  
   at C.Foo()
   at C.Bar()
   at C.Baz()
