builtins.def [...]: Require an explicit ATTRS argument.
* builtins.def [DEF_GCC_BUILTIN]: Require an explicit ATTRS argument. Mark BUILT_IN_RETURN, BUILT_IN_EH_RETURN, BUILT_IN_LONGJMP and BUILT_IN_TRAP as noreturn, the ISO C99 floating point unordered comparisons (e.g. __builtin_isgreater) as const, and leave the remaining GCC_BUILTINs unchanged. * c-decl.c (builtin_function): No need to explicitly mark BUILT_IN_RETURN and BUILT_IN_EH_RETURN as noreturn. * cp/decl.c (builtin_function_1): No need to explicitly mark BUILT_IN_RETURN and BUILT_IN_EH_RETURN as noreturn.
