Simple auto-LINQ-Sum() action.
Improved auto-LINQ sum to support several new cases.
Renamed AutoLinqSum to AutoLinqSumAction. Added support for additional statements, notably conditionals.
AutoLinqSumAction now fuses the Sum expression with the statement before the loop if appropriate.
AutoLinqSumAction: Now properly handles increment/decrement and Count().
Disabled AutoLinqSumAction if Enumerable cannot be resolved as System.Linq.Enumerable
