Auto merge of #43931 - eddyb:const-local-key, r=alexcrichton
Make the LocalKey facade of thread_local! inlineable cross-crate. Fixes (almost*) #25088 by changing the `LocalKey` `static` `thread_local!` generates to a `const`. This can be done because a `LocalKey` value holds no actual TLS data, only function pointers to get at said data, and it could even be made `Copy` without any negative consequences. The recent stabilization of rvalue promotion to `'static` allows doing this without changing the API. r? @alexcrichton *almost because we can't yet inline `__getit` because it breaks on MSVC, see https://github.com/rust-lang/rust/pull/43931#issuecomment-323534214
