Implement ftruncate64/ftruncate for File::set_len

This adds a shim for `ftruncate64` (on Linux) or `ftruncate` (on macOS) to enable support for `File::set_len`, and includes a test.

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.

45113eb6a4 Auto merge of #1325 - RalfJung:float_to_int_unchecked, r=RalfJung
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.

retag return place

@eddyb suggested that return places should be treated like unique references for Stacked Borrows. That is implemented by this patch, but it is unfortunately quite the hack because otherwise we are retagging *references*, not places.

@eddyb does this roughly correspond to what you had in mind? (Except for whatever it is you think should happen with argument passing, which is a much bigger issue.) Also, do you think there is any way we can *test* this?

Needs https://github.com/rust-lang/rust/pull/71100 to land.
