builtins.def (BUILT_IN_PRINTF, [...]): Changed from front-end builtins to normal builtins, using DEF_LIB_BUILTIN.


	* builtins.def (BUILT_IN_PRINTF, BUILT_IN_FPRINTF): Changed from
	front-end builtins to normal builtins, using DEF_LIB_BUILTIN.
	(BUILT_IN_PRINTF_UNLOCKED, BUILT_IN_FPRINTF_UNLOCKED): Changed
	from front-end to normal builtins, using DEF_EXT_LIB_BUILTIN.
	(DEF_FRONT_END_LIB_BUILTIN): Delete.
	(DEF_EXT_FRONT_END_LIB_BUILTIN): Delete.
	(BUILT_IN_FWRITE_UNLOCKED): Wrap long line.

	* builtins.c (build_string_literal): New function to construct
	a char* pointer to a string literal.
	(expand_builtin_fputs): Change 2nd argument from "int ignore" to
	"rtx target" to be consistent with other expand_builtin_* functions.
	Change 3rd argument from "int unlocked" to "bool unlocked".
	(expand_builtin_printf): Rewrite of c_expand_builtin_printf from
	c-common.c to avoid front-end dependencies.  Optimize printf("")
	as a no-op when the result isn't required.  Handle embedded NULs
	in format string.
	(expand_builtin_fprintf): A rewrite of c_expand_builtin_fprintf
	from c-common.c to avoid front-end dependencies.  Likewise, optimize
	fprintf(fp,"") as a no-op when the result isn't required, evaluating
	fp for side-effects.  Handle embedded NULs in format string.
	(expand_builtin_sprintf): Fix typo.
	(expand_builtin): Don't expand BUILT_IN_FPRINT{,_UNLOCKED} when not
	optimizing.  Adjust calls of expand_builtin_fputs to match the API
	change. Expand BUILT_IN_PRINTF and BUILT_IN_PRINTF_UNLOCKED using
	expand_builtin_printf.  Likewise, expand BUILT_IN_FPRINTF_UNLOCKED
	and BUILT_IN_FPRINTF using expand_builtin_fprintf.

	* c-common.c (is_valid_printf_arglist): Delete.
	(c_expand_builtin): Delete.
	(c_expand_builtin_printf): Moved to builtins.c. Delete.
	(c_expand_builtin_fprintf): Moved to builtins.c.  Delete.
	(c_expand_expr): No longer treat CALL_EXPRs specially.
	(CALLED_AS_BUILT_IN): Delete.
