	* cpplib.c (special_symbol): Rewrite.  Don't copy things
	  multiple times.  Handle __STDC__ specially.  T_CONST
	  indicates a constant /string/.  Don't handle T_*_TYPE and
	  T_SPEC_DEFINED.  Use cpp_buf_line_and_col instead of
	  adjust_position.  Determine the file buffer only if needed.
	  (initialize_builtins): Handle __SIZE_TYPE__,
	  __PTRDIFF_TYPE__, __WCHAR_TYPE__, __USER_LABEL_PREFIX__, and
	  __REGISTER_PREFIX__ with T_CONST special hashtab entries.
	  Don't provide __OBJC__; the driver does that.	 Provide
	  __STDC_VERSION__, using T_CONST.  Use T_STDC for
	  __STDC__.  Give install the length of all symbols defined.
	  (eval_if_expression): Drop code to insert and remove the
	  "defined" special symbol.
	* cpplib.h: Remove SELF_DIR_DUMMY (no longer used).  Remove
	  T_*_TYPE and T_SPEC_DEFINED from enum node_type; add T_STDC.
	* cpphash.c (install): Drop the `ivalue' parameter.  Constify
	  the `value' parameter.  All callers changed.
	* cpphash.h (install): Change prototype to match.
	  (union hashval): Remove `ival' member.
	* cppexp.c (cpp_lex): Handle `defined' here.

        for loop. Fixed comments. Continue target is current loop when
        unlabeled.

cost.
(load_multiple_sequence): Newer ARMs don't benefit from ldm if
the sequence is short.
(final_prescan_insn): Use max_insns_skipped instead of
