gcc/
	* optabs.h (optab_handler, convert_optab_handler): Delete.
	(OPTAB_HANDLER, SET_OPTAB_HANDLER): New macros.
	(CONVERT_OPTAB_HANDLER, SET_CONVERT_OPTAB_HANDLER): Likewise.
	* builtins.c: Replace optab_handler(X)->insn_code with
	OPTAB_HANDLER or SET_OPTAB_HANDLER thoughout.  Likewise
	convert_optab_handler(X)->insn_code with CONVERT_OPTAB_HANDLER
	and SET_CONVERT_OPTAB_HANDLER.
	* expmed.c, expr.c, genopinit.c, ifcvt.c, optabs.c, reload.c,
	reload1.c, stmt.c, targhooks.c, tree-ssa-loop-prefetch.c,
	tree-ssa-math-opts.c, tree-vect-data-refs.c, tree-vect-generic.c,
