[Mono-dev] Extract method name from IEnumerator

Hello Joachim,

JB summarized it nicely, you can use name inside <.> as original method 
name, there is couple of issue with it though.
It may change in the future and it ignores generic method and method 
overloads. Therefore if you need better name mapping you have to use our 
debug symbol file.
