This is to ensure that calls to `setjmp(3)` result in correct code generation that respects `setjmp(3)`'s `returns_twice` behavior. Otherwise, we might run into bugs (for example, Clang may perform tail-call optimization on this function if `-fno-builtins` is set (#122840)). --------- Co-authored-by: Nick Desaulniers <nick.desaulniers@gmail.com>
