[IronPython] Creating Dynamic Assemblies from IronPython 2.6

It's actually a CLR bug - we can't call this method from a dynamic method. We could probably add a workaround and force it to always be called via reflection.

I think this is something that broke well before the 2.0 release. To work around it in pyc.py, we added DefineDynamicAssembly to the PythonOps class in IronPython:
from IronPython.Runtime.Operations import PythonOps
assemblyBuilder = PythonOps.DefineDynamicAssembly(...)

I'm unable to create a Dynamic assembly from IronPython using
AppDomain.DefineDynamicAssembly. The Python file attached results in
the following error:
Traceback (most recent call last):
File "pinvoke.py", line 5, in pinvoke.py
File "mscorlib", line unknown, in DefineDynamicAssembly
File "mscorlib", line unknown, in InternalDefineDynamicAssembly
File "mscorlib", line unknown, in nCreateDynamicAssembly
File "mscorlib", line unknown, in CheckGrantSetHelper
SystemError: Object reference not set to an instance of an object.
The equivalent C# program (also attached) works fine. I'm guessing
there's something special about IronPython's AppDomain, but I'm not
sure what it is. This is using revision 48140. Any ideas?
