Subject: The fast-path still needs to set kill markers and spill/restore points as appropriate.

The fast-path still needs to set kill markers and spill/restore points as appropriate.
With this patch, all of MultiSource/Applications and all of SPEC2000/2006 pass with
the SimpleSpiller and this fast-path enabled.
