Squaring by means of mpz_mul is about 230 times faster on Ryzen 2700X
using current GMP code compared to the 1999 Pentium 3 with GMP 2.0.2.
For mpz_mod, the former system is about 110 times faster.
The speedup comes from several factors:
1. 64-bit vs 32-bit basic multiply insns gives 3x to 4x
2. Clock speed about 5x
3. Better GMP algorithms and implementations
