possible mpz_probab_prime_p speed-up

[Paul Underwood]

Dear members,

please see:-

1) my paper: https://mersenneforum.org/showpost.php?p=592064&postcount=1
2) the GMP code: https://mersenneforum.org/showpost.php?p=616574&postcount=21
3) the whole thread: https://mersenneforum.org/showthread.php?t=27288

Is there any interest in making this code native to GMP's mpz_probab_prime_p function?

Best

Paul Underwood
