Currently, all calculations over Ints and other machine types are always performed |0. For any expression where the end result will never exceed 2^52, this is unnecessary and could be replaced by a single |0 at the topmost level of the expression given that all atomic operands are guaranteed to be in range.
This could be done using range propagation, if we're to get fancy, or partially by applying some simple rules (X1 + X2 ... + Xn where `n < 52' is always safe, for instance).
