Use rtx_jump_table_data in jump.c:delete_related_insns
gcc/ChangeLog
2014-09-05 David Malcolm <dmalcolm@redhat.com>
* jump.c (delete_related_insns): Introduce a new local "table" by
replacing JUMP_TABLE_DATA_P with a dyn_cast, then use the
get_labels method of "table" to simplify access to the labels in
the jump table.
