Comment:

 The short answer is that gcd is different because only 1 Integer backend
 supports it; the others use the generic gcd implementation. This means
 that we get a little ugliness one way or another.

 But I've now changed the way it works so that, if
 `OPTIMISE_INTEGER_GCD_LCM` is defined, then we require that the integer
 library exports `gcdInt` as well as `gcdInteger`. So now we directly call
 the function that we want, rather than using rules.
