* domwalk.h (struct dom_walk_data): Remove all callbacks except
before_dom_children_before_stmts and after_dom_children_after_stmts.
Rename the two remaining callbacks to just before_dom_children and
after_dom_children. Remove other GIMPLE statement walking bits.
* domwalk.c (walk_dominator_tree): Remove now unsupported features.
* graphite.c: Do not include domwalk.h.
* tree-into-ssa.c (interesting_blocks): New global.
(struct mark_def_sites_global_data): Remove it and names_to_rename.
(mark_def_sites, rewrite_stmt, rewrite_add_phi_arguments,
rewrite_update_stmt, rewrite_update_phi_arguments): Simplify
now that they're not domwalk callbacks.
(rewrite_initialize_block): Rename to...
(rewrite_enter_block): ... this, place after called functions. Test
interesting_blocks, call rewrite_stmt and rewrite_add_phi_arguments.
(rewrite_finalize_block): Rename to...
(rewrite_leave_block): ... this, place after called functions.
(rewrite_update_init_block): Rename to...
(rewrite_update_enter_block): ... this, place after called functions.
Test interesting_blocks, call rewrite_update_stmt and
rewrite_update_phi_arguments.
(rewrite_update_fini_block): Rename to...
(rewrite_leave_block): ... this, place after called functions.
(rewrite_blocks): Remove last argument, simplify initialization of
walk_data.
(mark_def_sites_initialize_block): Rename to...
(mark_def_sites_block): ... this, call mark_def_sites.
(mark_def_sites_blocks): Remove argument, simplify initialization of
walk_data.
(rewrite_into_ssa): Adjust for interesting_blocks_being a global.
(update_ssa): Likewise.
* tree-ssa-dom.c (optimize_stmt): Simplify now that it's not a domwalk
callback.
(tree_ssa_dominator_optimize): Simplify initialization of walk_data.
(dom_opt_initialize_block): Rename to...
(dom_opt_enter_block): ... this, place after called functions. Walk
statements here, inline propagate_to_outgoing_edges.
(dom_opt_finalize_block): Rename to...
(dom_opt_leave_block): ... this, place after called functions.
* tree-ssa-dse.c (dse_optimize_stmt): Simplify now that it's not a
domwalk callback.
(dse_enter_block, dse_record_phi): New.
(dse_record_phis): Delete.
(dse_finalize_block): Rename to...
(dse_leave_block): ... this.
(tree_ssa_dse): Simplify initialization of walk_data.
* tree-ssa-loop-im.c (determine_invariantness, move_computations):
Adjust initialization of walk_data.
* tree-ssa-loop-unswitch.c: Do not include domwalk.h.
* tree-ssa-loop-phiopt.c (get_non_trapping):
Adjust initialization of walk_data.
* tree-ssa-loop-threadedge.c: Do not include domwalk.h.
* tree-ssa-uncprop.c (uncprop_into_successor_phis): Simplify now that
it's not a domwalk callback.
(uncprop_initialize_block): Rename to...
(dse_enter_block): ... this, call uncprop_into_successor_phis.
(dse_finalize_block): Rename to...
(dse_leave_block): ... this.
(tree_ssa_uncprop): Simplify initialization of walk_data.
* Makefile.in: Adjust dependencies.
