re PR bootstrap/44426 (gcc 4.5.0 requires c9x compiler to build)

	PR bootstrap/44426
	* tree.h (build_call_expr): Don't define as vararg macro, instead
	add a prototype.
	* builtins.c (build_call_nofold): Remove.
	(expand_builtin_int_roundingfn, expand_builtin_pow,
	expand_builtin_mempcpy_args, expand_builtin_stpcpy,
	expand_builtin_memset_args, expand_builtin_strcmp,
	expand_builtin_strncmp, expand_builtin_memory_chk): Use
	build_call_nofold_loc instead of build_call_nofold.
	(build_call_expr): New function.
