	* BinaryExpression.cs (EmitCoalesce): Add support for emitting
	code for Coalesce.

	TODO: this does not use the "Conversion" Lambda, which am not sure
	who generates this or what it is used for.

	(EmitLogical): Fix a couple of bugs in AndAlso, OrElse.

	* Expression.cs: Add support for Coalesce.
	(BinaryCoreCheck): Move more checking here, instead of the helper
	routines, will remove them next.

	* LambdaExpression.cs (Compile): Create the delegate last, so we
	manage to save the assembly while debugging in case of error
