83b4222d9a Auto merge of #1422 - RalfJung:cargo-miri-workspace, r=oli-obk 
Move cargo-miri into separate package

So far, `cargo-miri` depended on the Miri library crate. That was mostly for convenience (to avoid having to deal with workspaces), but also because until recently `cargo-miri` needed access to the ["Miri default flags"](af044209b0/src/lib.rs (L75)). But with `MIRI_BE_RUSTC` that is no longer the case, so we can remove this fake dependency. :)

@oli-obk what do you think? Also I expect the rustc bootstrap integration will need updates, hints would be appreciated. :D

351d46d3fb 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).

da940eb91f Auto merge of #1354 - divergentdave:dump-alloc-on-undef-read, r=RalfJung 
Print hex dump of alloc on reading undef bytes

Here's a small addition I made locally to the UB diagnostics, in case you're interested in it. This PR calls `dump_alloc()` on the relevant allocation if Miri fails on UB due to reading undefined bytes. This came in handy when diagnosing such an issue in a large program using unsafe Rust, in part because it wasn't deterministic enough to use `-Zmiri-track-alloc-id=`. If you'd like to put this behind another -Z flag, let me know.

Handle std::sync::atomic::spin_loop_hint()

This PR adds support for `std::sync::atomic::spin_loop_hint()` by implementing the `llvm.x86.sse2.pause` intrinsic when the target is x86-based. It appears this is the first LLVM intrinsic in foreign_items, so I added a couple match blocks to handle it or fall through to the different OS-specific methods. I added a basic smoke test to `tests/run-pass/sync.rs`. I came across this by way of `crossbeam::utils::Backoff::spin()`, FWIW.

implement float_to_int_unchecked

@hanna-kruppe would be great if you could have a look at this.

`float.rs` tests legal casts. `test_cast` checks that both `as` casts and unchecked casts work (i.e., these are not saturating). The `compile-fail` tests should ensure that illegal casts via the intrinsic are detected as such.

Includes shims for `QueryPerformanceCounter` & `QueryPerformanceFrequency` in Windows, which are both called in Windows when `std::time::Instant` is created.

Windows docs page ["Acquiring high-resolution time stamps"](https://docs.microsoft.com/en-us/windows/win32/sysinfo/acquiring-high-resolution-time-stamps) was helpful in learning how `QueryPerformanceCounter` & `QueryPerformanceFrequency` work.

Abort instead of panic on asserting intrinsics

This fixes #1222
replacing the panic with an abort and a corresponding message.
the stack trace is already printed, this just adds an optional message the caller can pass, and I just pass the same message we passed to the panic but now to the abort instead.
