Yet another version, with discrete up update (I could not get any
speedup by doing the same for rp). Now runs at 3.75 c/l on A9:

$ GMP_CPU_FREQUENCY=1e9 ./speed -s1000-1020  -C mpn_submul_1.17
clock_gettime is 1.000ns accurate
overhead 8.95 cycles, precision 1000 units of 1.00e-06 secs, CPU freq 1000.00 MHz
        mpn_submul_1.17
1000           3.7381
1001           3.7436
1002           3.7531
1003           3.7235
1004           3.8119
1005           3.8081
1006           3.7250
