Add default impls for `FileDescriptor` methods

I felt like it was just noisy to have to write the "can't do this here" defaults

adjust for more backtrace pruning

The Miri side of https://github.com/rust-lang/rust/pull/99690. Those messages are much nicer. :) And we also need error-pattern much less.

3d237be15c Auto merge of #2436 - RalfJung:lib-crates, r=oli-obk 
fix build.rs invoking RUSTC to do check builds

This makes the Miri driver, when invokved via the RUSTC env var from inside a build script, behave almost entirely like rustc. I had to redo how we propagate sysroot information for this (which is actually back to how we used to do sysroot propagation many years ago).

Fixes https://github.com/rust-lang/miri/issues/2431

d905901d65 make miri a better RUSTC by default inside cargo-miri 
this requires a change in sysroot handling: miri driver now requires
MIRI_SYSROOT to be set when it is in 'target' mode, rather than relying on
`--sysroot` always being present.

17bb2c0946 Auto merge of #2428 - RalfJung:cargo-miri-runner, r=RalfJung 
cargo-miri: use '--config target.runner' rather than the TARGET_RUNNER env vars

That means we can properly escape spaces in our filename. This should fix https://github.com/rust-lang/miri/issues/2417, hopefully for real this time. We can also specify a "leading command" which makes it much easier to disambiguate runner invocations from rustdoc invocations!

Thanks to `@ehuss` for suggesting this.

b2418e82d3 Auto merge of #2425 - RalfJung:hide-xargo, r=RalfJung 
don't dump xargo output onto users of 'cargo miri test'

The xargo invocation prints a lot of details users probably won't care about, so let's hide them (unless the user did `cargo miri setup`, then we still print everything).

302e9ae206 Auto merge of #2424 - RalfJung:weak-memory-debug, r=RalfJung 
add a flag to print a diagnostic when an outdated value is returned from an atomic load

Helps with https://github.com/rust-lang/miri/issues/2313. It can still be annoying to figure out *which* outdated load is the important one in case there are many of them (and the issue contains some ideas for how to help with that situation), but having this flag is better than nothing.

Thanks to `@cbeuw` for the [original patch](64d738cb00) that I based this on.
