C TODO
C  * Clean up variable names, and try to decrease the number of distinct
C    registers used.
C  * Cleanup feed-in code to not require zeroing several registers.
C  * Make sure we don't depend on uninitialized predicate registers.
C  * We currently cross-jump very aggressively, at the expense of a few cycles
C    per operation.  Consider changing that.
C  * Could perhaps save a few cycles by using 1 c/l carry propagation in
C    wind-down code.
C  * Ultimately rewrite.  The problem with this code is that it first uses a
C    loaded u value in one xma pair, then leaves it live over several unrelated
C    xma pairs, before it uses it again.  It should actually be quite possible
C    to just swap some aligned xma pairs around.  But we should then schedule
C    u loads further from the first use.
