Debug ranges wrong in for loop with non-int32 counters

[KevinRansom]

This was originally opened on CodePlex by latkin

If I define a simple for loop with a signed-integer counter, debug behavior is as expected:

But if I change the counter to something besides a normal signed int (e.g. an unsigned int, shown below), line #2 takes 2 debug steps to pass through:

->

vs
-> -->

From peeking at the IL, looks like first example is compiled as normal ‘for’ loop as in C#, but second example is implemented with an IEnumerable and various plumbing to work with it.

Possibly we could generate the same optimized loop code for all integer types
