Following up on the previous patch, this patch makes
noce_convert_multiple emit two cmov sequences: The same one as before
and a second one that tries to re-use the existing CC. Then their costs
are compared and the cheaper one is selected.

Hi,
v2 now properly gets the reversed CC comparison. It also handles a cost2
== 0 situation that would prefer an empty seq2 before.
