more complete patch to resture DCE of killing defs
It still breaks in some cases. With the unfortunate fact that we need the
VMAYUSEs even for killing defs we might end up to need to do a two-phase DCE
for those :/ (See the special casing of PHI_NODEs in the patch, it seems some
more special casing is missing)
