This is the first (known) step towards starting to use `unix_sigpipe` in the wild. Eventually, `rustc_driver::set_sigpipe_handler` can be removed and all clients can use `unix_sigpipe` instead. For now we just start using `unix_sigpipe` in once place: `rustc` itself. It is easy to manually verify this change. If you remove `#[unix_sigpipe = "sig_dfl"]` and run `./x.py build` you will get an ICE when you do `./build/x86_64-unknown-linux-gnu/stage1/bin/rustc --help | false`. Add back `#[unix_sigpipe = "sig_dfl"]` and the ICE disappears again.
These targets have system limits on the thread names, 16 and 64 bytes respectively, and `pthread_setname_np` returns an error if the name is longer. However, we're not in a context that can propagate errors when we call this, and we used to implicitly truncate on Linux with `prctl`, so now we manually truncate these names ahead of time.

…h726 rustc: Use `unix_sigpipe` instead of `rustc_driver::set_sigpipe_handler` This is the first (known) step towards starting to use `unix_sigpipe` in the wild.

Add back `#[unix_sigpipe = "sig_dfl"]` and the ICE disappears again. PR that added `set_sigpipe_handler`: rust-lang#49606 Tracking issue for `unix_sigpipe`: rust-lang#97889 Not sure exactly how to label this PR. Going with T-libs for now since this is a T-libs feature. ``@rustdoc`` labels +T-libs
Prevent foreign Rust exceptions from being caught Fix rust-lang#102715 Use the address of a static variable (which is guaranteed to be unique per copy of std) to tell apart if a Rust exception comes from local or foreign Rust code, and abort for the latter.
