    libstdc++: Guard use of sized deallocation [PR114940]

    Clang does not enable -fsized-deallocation by default, which means it
    can't compile our <stacktrace> and <generator> headers.

    Make the __cpp_lib_generator macro depend on the compiler-defined
    __cpp_sized_deallocation macro, and change <stacktrace> to use unsized
    deallocation when __cpp_sized_deallocation isn't defined.

    libstdc++-v3/ChangeLog:

            PR libstdc++/114940
            * include/bits/version.def (generator): Depend on
            __cpp_sized_deallocation.
            * include/bits/version.h: Regenerate.
            * include/std/stacktrace (_GLIBCXX_SIZED_DELETE): New macro.
            (basic_stacktrace::_Impl::_M_deallocate): Use it.
