I don't understand. Exactly what mess did I make?
We also probably have to set SSA_NAME_DEF_STMT to NULL in bsi_remove in order to
be sure that an SSA name with no uses isn't actually associated with a stmt any
more (you can have valid defs with no uses). It is set when the SSA_NAME is
created, but I don't think that field ever gets cleared anywhere else.
