Simon Dardis 1134b2a24b Infer lowest bits of an integer Multiply when the low bits of the operands are known ...

When the lowest bits of the operands to an integer multiply are known, the low bits of the result are deducible.
Code to deduce known-zero bottom bits already existed, but this change improves on that by deducing known-ones.
