Auto merge of #94040 - Mark-Simulacrum:destabilize-load-store, r=Amanieu

Destabilize cfg(target_has_atomic_load_store = ...)

This was not intended to be stabilized yet.

This keeps the cfg_target_has_atomic feature gate name since compiler-builtins otherwise depends on it and I'd rather not try to manage a bump across a crates.io published repository given the time-sensitivity here (we need to land this quickly to avoid a beta backport).

Closes https://github.com/rust-lang/rust/issues/32976
