This is a reland of 548fda4afb
regress-1054466 is modified to not use 64x2 operations, since that was
causing problems on noavx/nosse builds, which requires scalar lowering,
and scalar lowering for 64x2 ops is not implemented.
Original change's description:
> [liftoff] Check fp_pair when looking up register for reuse
>
> Given two registers that are both not gp_pair, one could be an fp_pair,
> and the other not, and we will incorrect call == on them. The current
> check needs to be expanded to check that both registers are fp_pair.
