* flow.c (propagate_block_delete_insn): Handle deletion of ADDR_VEC
and ADDR_DIFF_VEC insns when the proceeding CODE_LABEL was put
into the constant pool.
* jump.c (jump_optimize_1): Remove barrier successors after all
the LABEL_NUSES counds have been computed.
(delete_barrier_successors): When deleting a tablejump insn, also
delete the jump table it uses.
* varasm.c (force_const_mem): Set LABEL_PRESERVE_P when forcing a
label into memory.
