Implement 64bit multiplication in terms of efficient 64x64=int128. #26

Closed jaykrell closed 3 years ago

jaykrell commented 3 years ago

On AMD64, the exact same multiplication is done, at least in the full 64x64 case (probably same as 32x64 also).

Note that the "intrinsic" function names could be reused here, making the diff much smaller.

This is fixed, though slightly differently, in fix/intrinsic branch. Please review, and I'll merge that branch into main.
