Since X may point to the same MPI as either G or L (or even both), we
can't set the carry flag based on the contents of G or L after having
modified X. Instead, compute and stash the new carry value first.

WIP: implement subtraction correctly. The actual result is now correct
most of the time, but the MSB calculation is not.

In both mpi_add_abs() and mpi_sub_abs(), make sure that the target is
untouched if the operation fails. Also ensure that A = A +/- A works.
