Martin Hořeňovský d99eb8bec8 Optimize 64x64 extended multiplication implementation ...

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.
