tree.c, tree.h: Change tree_code_type, tree_code_length, and tree_code_name from pointers to arrays.

        * tree.c, tree.h: Change tree_code_type, tree_code_length, and
        tree_code_name from pointers to arrays.
        * tree.c: Remove standard_tree_code_* variables, no longer used.
        * print-tree.c: Remove declaration of tree_code_name.

        * cp/lex.c (init_lex): Update for tree_code_* changes.
        * objc/objc-act.c (init_objc): Likewise.

        * tree.def, cp/cp-tree.def, objc/objc-tree.def: Update for tree_code
        changes.
