Uday Bondhugula 36a415bcc5 More affine expr simplifications for floordiv and mod 
Add one more simplification for floordiv and mod affine expressions.
Examples:
 (2*d0 + 1) floordiv 2 is simplified to d0
 (8*d0 + 4*d1 + d2) floordiv 4 simplified to 4*d0 + d1 + d2 floordiv 4.
 etc.

 Similarly, (4*d1 + 1) mod 2 is simplified to 1,
            (2*d0 + 8*d1) mod 8 simplified to 2*d0 mod 8.

Change getLargestKnownDivisor to return int64_t to be consistent and
to avoid casting at call sites (since the return value is used in expressions
of int64_t/index type).
