cmd/compile: ensure register args come before on-stack args in schedule

The register allocator doesn't like OpArg coming in between other
OpIntArg operations, as it doesn't put the spills in the right place
in that situation.

This is just a bug in the new scheduler, I didn't copy over the
proper score from the old scheduler correctly.
