Apparently I looked at the docs for umulh when checking availability,
and umul128 is x64 only.

Now we use intrinsics when possible, and fallback to optimized
implementation in portable C++. The difference is about 4x when
we can use intrinsics and about 2x when we cannot.

This should speed up our Lemire's algorithm implementation nicely.
