Add FIXME comments to from_ascii_bytes_radix_impl #164881 (Add FIXME comments to from_ascii_bytes_radix_impl)

GenMC now supports weak CASes and the failure ordering of CASes. Hence, the CAS API is adjusted accordingly (no change in behavior for now).

Modeling spurious failures is opt-in (see `-Zmiri-genmc-weak-cas-spurious-failures`), since Miri-GenMC cannot bound all retry loops involving weak CASes (e.g., the ones in the standard library).

…al-context-ref-readonly Use `eval_context_ref` where mutable access is not needed

Update subtree sync docs

support __cxa_thread_atexit_impl and correctly handle thread cleanup on exit

Letting #162808 go in its own PR, that might fail in some weird places.
