The error message is not entirely right now, but close enough... let's get CI to pass before we miss other breakage.

Remove unwrap_none/expect_none, take 2.

This is https://github.com/rust-lang/miri/pull/1734, but now with a better alternative.

This also upgrades rustc to the latest version, to be able to use the better alternative (`try_insert`).

0a0e366ccf Auto merge of #1733 - Smittyvb:breakpoint-intrinsic, r=RalfJung
Support breakpoint intrinsic

The `breakpoint` intrinsic raises a `SIGTRAP` signal. If a debugger is attached to a normal program, then `SIGTRAP` can be used to trigger breakpoints in debuggers like `gdb`. If there is no debugger, then the program exits with a message like `Trace/breakpoint trap (core dumped)`. This adds support for the intrinsic in Miri. While actually passing through the `SIGTRAP` doesn't make sense in a Miri context (if it just raised the signal normally then it would allow for debugging Miri itself, not the program being evaluated). As such, it just raises an error.

rename atomic_op_min_max -> atomic_op

The corresponding enum is called `AtomicOp` so IMO this also makes more sense as the name for the function.

`RUST_TEST_NOCAPTURE` seems to make no difference except for making compiletest output not use colors any more; `RUST_BACKTRACE` is already set by `compiletest.rs`.

rustup; fix tests for new MIR optimization

Somehow https://github.com/rust-lang/rust/pull/78360 manages to mask UB. This would make sense if there were loops or things like that, but there are not, so really this is just very confusing...

fix reborrowing of tagged ZST references

`@SkiFire13` [pointed out](https://github.com/rust-lang/rust/pull/82554#issuecomment-787088712) that Miri fails to detect illegal use of empty slices. This PR fixes that. In so doing, it uncovers a flaw of Stacked Borrows: it is incompatible with how the formatting machinery uses `extern type`, so for now we skip reborrowing when we cannot determine the exact size of the pointee.
