When we encounter a DW_OP_implicit_value we call store_implicit_value ()
which will try to store the value as part of the Dwarf dbg. But if we are
examining CFI there will be no Dwarf dbg. And DW_OP_implicit_value should
not be part of CFI. So explicitly reject it in store_implicit_value if
dbg is NULL.
