Speed up walk_tree by introducing a special-purpose hash table.
* pointer-set.c: New file, special-purpose hash table.
* pointer-set.h: New file.
* tree.h (struct pointer_set_t): Declare as opaque type.
(tree_walk): Last argument is pointer_set_t* now.
* tree-inline.c (WALK_SUBTREE): Convert from htab to pset.
(walk_type_fields):
(walk_tree): Convert from htab_t to pointer_set_t for keeping
track of which nodes have already been visited.
(walk_tree_without_duplicates): Convert from htab_t to pointer_set_t.
* cgraphunit.c (cgraph_create_edges): Likewise.
(cgraph_characterize_statics_local): Likewise.
* tree-dfa.c (collect_dfa_stats): Likewise.
* langhooks-def.h (lhd_tree_inlining_walk_subtrees): Last arg is
pointer_set_t* now.
* langhooks.c (lhd_tree_inlining_walk_subtrees): Likewise.
* langhooks.h (struct lang_hooks_for_tree_inlining): Last arg type
of walk_subtrees is pointer_set_t* now.
* Makefile.in (OBJS-common): add pointer-set.o
(tree-inline.o): Depends on pointer-set.h
(tree-dfa.o): Likewise
(cgraphunit.o): Likewise
* cp/Make-lang.in (pt.o): depends on pointer-set.h
* cp/cp-tree.h (cp_walk_subtrees): Last argument is pointer_set_t* now.
* cp/pt.c (struct pair_fn_data): Use pointer_set_t, not htab_t
(for_each_template_parm): Convert from htab_t to pointer_set_t.
* cp/tree.c (cp_walk_subtrees): Last argument is pointer_set_t* now.
* java/lang.c (java_tree_inlining_walk_subtrees): Last arg is struct
pointer_set_t* now.
