        PR middle-end/71876
        * calls.c (special_function_p): Remove special handling of
        "setjmp_syscall", "qsetjmp", "longjmp", "siglongjmp" and the
        prefix "__x".  Recognize "savectx", "vfork" and "getcontext" only
        without prefix.  Remove potentially unsafe ECF_LEAF and ECF_NORETURN.
