It doesn't check the cases where both input operands overlap some output
operands, e.g.,
mpz_gcdext (res1, res2, res3, res1, res3);
or
mpz_gcdext (res1, res2, res3, res2, res2);
Should it do that, or is it enough that the reuse tests overlap one
operand at a time? Doing all combinations everywhere does blow up the
number of tests a bit.
Let's make the test slower as a reaction to Vincent's complaint! :-)
Seriously, I think we should exercise all combinations.
