Limitations:
- Don't blindly use this to set UMUL_TIME in gmp-mparam.h, check the code
- generated first, especially on CPUs with low latency multipliers.
-
The default umul_ppmm doing h*l will be getting increasing numbers of
high zero bits in the calculation. CPUs with data-dependent multipliers
will want to use umul_ppmm.1 to get some randomization into the
