Since ~B + B == -1, the maximum value for A that saturates is ~B. For ussub, we only have to consider underflow. The minimum value that saturates to 0 from A - B is B.

So remove the difference between 32- and 64-bit hosts.

It does not work to use this for a uint64_t value that happens to be small enough to fit in tcg_target_ulong.

Only implement left-rotate for now, as the only known use of vector rotate by scalar is s390x, so any right-rotate would be unused and untestable.

However, we actually perform the same expansion in do_gvec_shifts, so it is also unneeded. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
