* tree-ssa-ccp.c (ccp_propagate::visit_phi): Avoid excess
vertical space in dumpfiles.
* tree-ssa-propagate.h
(ssa_propagation_engine::process_ssa_edge_worklist): Remove.
* tree-ssa-propagate.c (cfg_blocks_back): New global.
(ssa_edge_worklist_back): Likewise.
(curr_order): Likewise.
(cfg_blocks_get): Remove abstraction.
(cfg_blocks_add): Likewise.

(add_ssa_edge): Add to current or next worklist based on
RPO index.
(add_control_edge): Likewise.
(ssa_propagation_engine::process_ssa_edge_worklist): Fold
into ...
(ssa_propagation_engine::ssa_propagate): ... here. Unify

over iteration.
(ssa_prop_init): Allocate new worklists, do not dump
immediate uses.
(ssa_prop_fini): Free new worklists.
