Auto merge of #1284 - vakaras:add-threads-cr2, r=RalfJung
...
Implement basic support for concurrency (Linux/macos only)
Changes (most new code is in `src/threads.rs` and `src/shims/foreign_items/posix.rs`):
1. Move the stack from `Machine` to a newly created `Thread` struct.
2. Add a `ThreadSet` struct that manages the threads.
3. Change `canonical_alloc_id` to create a unique allocation id for each thread local and thread (the responsible struct is `ThreadLocalStorage`)
4. Change the code to execute the thread local destructors immediately when a thread terminates.
5. Add the most basic round-robin scheduler.
This pull request depends on [these changes to the compiler](https://github.com/rust-lang/rust/pull/70598 ).
