* bb-reorder.c (reorder_block_def): Reorder elements for size.
Remove add_jump; add next; replace flags with visited.
(rbd_init): Remove.
(REORDER_BLOCK_HEAD, REORDER_BLOCK_VISITED): Remove.
(REORDER_BLOCK_FLAGS, REORDER_BLOCK_INDEX): Remove.
(REORDER_BLOCK_ADD_JUMP, REORDER_BLOCK_EFF_HEAD): Remove.
(REORDER_BLOCK_EFF_END, REORDER_BLOCK_SCOPE): Remove.
(RBI): New.
(reorder_index, reorder_last_visited): Remove.
(skip_insns_after_block): Rewrite to use a switch.
(get_common_dest): Remove.
(chain_reorder_blocks): Remove.
(record_effective_endpoints): Split out from reorder_basic_blocks.
(make_reorder_chain): Likewise. Loop until all blocks are placed.
(make_reorder_chain_1): Renamed from old make_reorder_chain.
Only construct the reorder chain, do not move insns. Try harder
to tail recurse.
(label_for_bb, emit_jump_to_block_after): New.
(fixup_reorder_chain): Use them. Do bulk block movement. Examine
and adjust the jump insns appropriately. Fixup basic_block_info.
(verify_insn_chain): Always define.
(relate_bbs_with_scopes): Call xmalloc, not xcalloc. Fix thinko
in allocation size.
(make_new_scope): Don't write zeros to calloc'd space.
(build_scope_forest): Rely on xrealloc to DTRT.
(reorder_basic_blocks): Don't build loop nest. Don't fail if
profile_arc_flag. Streamline EH test.
* flow.c (redirect_edge_succ, redirect_edge_pred): New.
* basic-block.h: Declare them.
