Optimize smallish mpz to native int conversion

* src/bignum.c (make_integer_mpz, mpz_to_intmax):
If FASTER_BIGNUM, optimize the common case where the value fits in
long int.  In this case we can use mpz_fits_slong_p and mpz_get_si
instead of looping with mpz_getlimbn.
(mpz_to_uintmax): Likewise for unsigned long int and mpz_get_ui.

(cherry picked from commit 0c850df888ebb68096a82ab32089e809de591620)
