Original change's description:
> [compiler] Make ReduceWord32EqualForConstantRhs work for Word64Equal
>
> Adds reduction case in MachineOperatorReducer for when the left-hand side of a
> Word64Equals is based on a 64-bit shift-and-mask operation, as is the case
> when Torque accesses 64-bit bitfields.
>
> This improves Speedometer2 by 0.15% on a Neoverse-N1 machine, with
> React-Redux being improved by 0.4%.
