    tree-optimization/105043: Object Size Checking docs cleanup

    Break the _FORTIFY_SOURCE-specific builtins out into a separate
    subsection from Object Size Checking built-ins and mention
    _FORTIFY_SOURCE in there so that the link between the object size
    checking builtins, the helper builtins (e.g. __builtin___memcpy_chk) and
    _FORTIFY_SOURCE is clearer.

    gcc/ChangeLog:

            PR tree-optimization/105043
            * doc/extend.texi (Object Size Checking): Split out into two
            subsections and mention _FORTIFY_SOURCE.
