 Current implementation of 'integer-gmp' uses only a subset of "bit
 fiddling" features, [http://gmplib.org/manual/Integer-Logic-and-Bit-
 Fiddling.html provided] by the GMP library. The ones missing are:

 {{{
 * mpz_popcount
 * mpz_setbit
 * mpz_clrbit
 }}}

 I think it would be nice to add these functions in addition to
 'testBitInteger'. Would you accept a patch?
