numeric for expr broken

[Chuck]

This test case results in bogus errors due, at least in part, to bad C# code gen:

class X

        def main is shared
                n = 5
                stuff = for i in n get .thing(i)
                trace stuff

        def thing(i as int) as Object is shared
                return i*i

Clarification.
This works correctly when the method called takes an int and returns one

def thing(i as int) as int is shared
    return i*i

It fails in all other cases with an error message from the C# compiler
like:

NumFor.cobra(10) error: The best overloaded method match for Cobra.Lang_ert_9ab85f7adadc1e32eda903e79ed62744.CobraImp.For<int,string>(int, int, int, Cobra.Lang_ert_9ab85f7adadc1e32eda903e79ed62744.CobraImp.ForGet<int,int>)" has some invalid arguments (C#)
NumFor.cobra(10): error: Argument "4": cannot convert from "anonymous method" to "Cobra.Lang_ert_9ab85f7adadc1e32eda903e79ed62744.CobraImp.ForGet<int,int>" (C#)

This "Cobra.Lang_ert_9ab85f7adadc1e32eda903e79ed62744" indicates the C# compiler is complaining about a mismatch against a generic method in the csharp RTL code. (BackEndClr/Native.cs).

It appears the generic method may be unnecessarily restrictive.

patch, test and relnote.

Thanks. Patch applied in changeset:2213

Note that it wasn't just methods that caused the problem. Any expression for the get that had a non-int type would cause the problem. So I added a little more test code and dropped "-method" from the filename.
