	* iterators.cs (MarkYield): track whether we are in an exception,
	and generate code accordingly.  Use a temporary value to store the
	result for our state.

	I had ignored a bit the interaction of try/catch with iterators
	since their behavior was not entirely obvious, but now it is
	possible to verify that our behavior is the same as MS .NET 2.0

	Fixes 54814
