Support Long and Char in const-bounded counter loop generation

If the loop end value is a compile-time constant (best we can do now),
and it is safe to iterate over a given range using "naive" for loop
(using '<=' or '>=' in loop condition),
generate such loops for Longs and Chars as well Ints (Bytes, Shorts).
