Nobuyoshi Nakada c14f230b26 Assign temporary ID to anonymous ID [Bug #18250]
Dumped iseq binary can not have unnamed symbols/IDs, and ID 0 is
stored instead.  As `struct rb_id_table` disallows ID 0, also for
the distinction, re-assign a new temporary ID based on the local
variable table index when loading from the binary, as well as the
parser.
