Since I cannot test this at all (qemu-system-sparc64 persistenty resists
all my usage attempts) I need you to perform the following tests:
Make sure the new code is used.
try -s1-10 mpn_add_n mpn_sub_n mpn_mul_1 mpn_addmul_1 mpn_submul_1
This tests functionality, and that no reads or writes are made outside
of the defined operands.
The -s1-10 argument is not universal. Complex, deeply pipelined code
might need a larger upper bound.
