Optimize the implementation of minusInteger in the integer-gmp package
As mentioned in https://www.fpcomplete.com/blog/2016/05/weigh-package, the current implementation of minusInteger is
minusInteger x y = inline plusInteger x (inline negateInteger y)which always allocates an additional integer. This could be improved by not always calling negateInteger and instead having an implementation more like plusInteger's.
