If the variable does not need a destructor, `std` uses racy initialization for creating TLS keys on Windows. With just the right timing, this can lead to `TlsFree` being called. Unfortunately, with rust-lang#132654 this is hit quite often, so miri should definitely support `TlsFree` ([documentation](https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-tlsfree)). I'm filing this here instead of in the miri repo so that rust-lang#132654 isn't blocked for so long.
