[Bug libstdc++/105562] [12/13 Regression] std::function::_M_invoker may be used uninitialized in std::regex move with -fno-strict-aliasing since r12-6216-g5a431b60d1f22199

Since r12-2468 it should be impossible for those members to be uninitialized,
and valgrind shows no uninitialized data. I think this is a compiler bug.

That only changed how -Wsystem-headers affects warnings (and not an improvement
IMHO).

The bogus warning was already present before then if you use -Wsystem-headers
