Chris Denton a9f8f8b070 Rollup merge of #122583 - Zoxc:tls-non-mut, r=joboet ... Use `UnsafeCell` for fast constant thread locals This uses `UnsafeCell` instead of `static mut` for fast constant thread locals. This changes the type of the TLS shims to return `&UnsafeCell<T>` instead of `*mut T` which means they are always non-null so LLVM can optimize away the check for `Some` in `LocalKey::with` if `T` has no destructor. LLVM is currently unable to do this optimization as we lose the fact that `__getit` always returns `Some` as it gets optimized to just returning the value of the TLS shim.		2024-03-16 18:27:34 +00:00
