2010-04-12  Miguel de Icaza  <[email protected]>

	* Enumerable.cs: Jumbo patch that inlines code, mainly for the AOT
	scenario where we our compiler cant infer the extra layer of
	indirection of a lambda function.

	But additionally, since we lack support for our JIT to inline
	intermediate delegate calls, it should save memory and run
	faster.
