[Reassociate] Don't canonicalize x + (-Constant * y) -> x - (Constant * y)..
..if the resulting subtract will be broken up later. This can cause us to get
into an infinite loop.
x + (-5.0 * y) -> x - (5.0 * y) ; Canonicalize neg const
x - (5.0 * y) -> x + (0 - (5.0 * y)) ; Break up subtract
x + (0 - (5.0 * y)) -> x + (-5.0 * y) ; Replace 0-X with X*-1.
