S/390: Define TARGET_BUILTIN_DECL

gcc/ChangeLog:
	* config/s390/s390.c: (enum s390_builtin, s390_expand_builtin):
	Rename S390_BUILTIN_max to S390_BUILTIN_MAX.
	(s390_builtin_decls): New array.
	(s390_init_builtins): Put builtin decls into s390_builtin_decls.
	(s390_builtin_decl): New function.
	(TARGET_BUILTIN_DECL): Define macro.
