[IronPython] __dict__ of exception instances

[Michael Foord]

Hello guys,

Attempting to access the '__dict__' attribute of a SyntaxError exception
in IP2a8 *returns* an 'OperationFailed' object.

The codeop module (Python standard library) compiles source code and
*compares* the __dict__ attribute of SyntaxError exception instances...

(I can work around this bug for the interactive interpreter...)
