  A crude test generator:

A slightly better variant.  It expects an argument, either "add" or
"sub", allowing it to test both add_ssaaaa and sub_ddmmss.

This version should work fine on 32-bit systems without modification.

This code is not well-defined (as Vincent might point out) as it
converts between signed and unsigned quantities in the range where the
signed number is negative.  But it does the job I intended it to do.

I will integrate this in some form in the GMP test facility.
