-C TODO
-C * Further optimize feed-in and wind-down code, both for speed and code size.
-C * Handle low limb input and results specially, using a common stf8 in the
-C epilogue.
-C * Use 1 c/l carry propagation scheme in wind-down code.
-C * Use extra pointer register for `up' to speed up feed-in loads.
-C * Work out final differences with addmul_1.asm.
