Fix incdec of referenced properties
I thought these SEPARATE_ZVAL_IF_NOT_REF usages were safe at first,
because incdec op supports reference variables. However this
violates the constraint that IS_TMP_VAR variables may not be
references (which is an issue if you use the result of the incdec
op).
Still need to fix the cases where read_property/write_property is
used.
