This relands commit d3e9aade0f. The original CL was reverted speculatively but didn't cause the buildbot failure.
Original change's description:
> [Interpreter] Move BinaryOp Smi transformation into BytecodeGenerator.
>
> Perform the transformation to <BinaryOp>Smi for Binary ops which take Smi
> literals in the BytecodeGenerator. This enables us to perform the
> transformation for literals on either side for commutative operations, and
> Avoids having to do the check on every bytecode in the peephole optimizer.
>
> In the process, adds Smi bytecode variants for all binary operations, adding
> - MulSmi
> - DivSmi
> - ModSmi
> - BitwiseXorSmi
> - ShiftRightLogical
>
