Fold equiv_hash, equiv_eq and equiv_free into new struct val_ssa_equiv_hasher. Renamed variables equiv_hash_elt to an_equiv_elt because of name ambiguity with struct type. Changed equiv_hash_elt_p to an_equiv_elt_p to match. * tree-ssa-phiopt.c'seen_ssa_names Fold name_to_bb_hash and name_to_bb_eq into new struct ssa_names_hasher. * tree-ssa-structalias.c'pointer_equiv_class_table * tree-ssa-structalias.c'location_equiv_class_table Fold equiv_class_label_hash and equiv_class_label_eq into new struct equiv_class_hasher. * tree-ssa-structalias.c'shared_bitmap_table Fold shared_bitmap_hash and shared_bitmap_eq into new struct shared_bitmap_hasher. * tree-ssa-live.c'var_map_base_init::tree_to_index New struct tree_int_map_hasher. * tree-sra.c'candidates Fold uid_decl_map_hash and uid_decl_map_eq into new struct uid_decl_hasher. This change moves the definitions from tree-ssa.c into tree-sra.c and removes the declarations from tree-flow.h tree-browser.c Remove stale declaration of removed TB_parent_eq. Fix template parameter for base class to match value_type. gimple.h Use gimplify_hasher::hash rather than gimple_tree_hash in the assertion check. Change return values to match return type.
