If GMP is used, it's definitely worth to have a non-GMP representation
for small integers, because GMP itself does not do it. A GMP integer
is represented by a pointer to digits, the allocated size, and the used
size multiplied by the sign; no special cases here.
(The fact that GMP does not do it is good for people who want to make
a super-compact representation themselves. GMP optimization for the same
case would be wasted. It requires some work for implementing overflow
detection, but it yields a very good final result.)
The major technical problem with GMP is that an out of memory condition
during computation is a fatal error, GMP does not provide a way to
recover from it.
