Should we specialise code in mpq_cmp so that it is faster when a
denominator is 1? Then write:
Absolutely worth considering.
mpq_cmp_z (mpq_srcptr q, mpz_srcptr z)

static const mp_limb_t dummy = 1;
mpq_t qz;
SIZ(NUM(qz)) = SIZ(z);

Before the changes I just pushed, I simply reordered the steps in the loop
to shorten the first and the last iteration in the loop...
Resulting in even better performance, I presume?
