bind_back cannot be compiled with G++ and -fno-delete-null-pointer-checks

LLVM build failed via g++-13 and `-fno-delete-null-pointer-checks` with the following error:

The code above was introduced by [PR-175056](https://github.com/llvm/llvm-project/pull/175056). It seems to be related to _probably_ a GCC bug, see [bug#97913](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97913). So, this is _probably_ not an issue of LLVM, but rather GCC.

Still this situation means LLVM cannot be build with GCC and extra safety flags, such as `-fno-delete-null-pointer-checks`, so I wonder if it'd be a good idea to modify LLVM's source code somehow to work-around the issue?
