We currently don't support stepping into a static class .cctor.

The only way of debugging these is stetting a breakpoint.

>From a technical point of view, stepping into the .cctor isn't really the
problem, stepping out of it is.  The problem is that these are called from the
runtime, so we'd leave the user stuck inside the runtime having to either
single-step or 'finish' out.

For instance look at the following test case:

=====
using System;

public class C
{
    public static void Main ()
    {
        string s = new string ('v', 1);
        Console.WriteLine (s);
    }
}
=====

If you try to 'step' into the Console.WriteLine(), we're currently skipping its
cctor.

I could easily add code to make the debugger stop in the .cctor, but when you
step out of it, you can't get into the Console.WriteLine() anymore without
manually stepping through a lot of unmanaged runtime code.

I have some ideas how to fix this, but it'll require some work to do this
right.

Fixing this will also get us a little closer to just-my-code debugging.
