Add targets for HermitCore (https://hermitcore.org) to the Rust compiler and port libstd to it.
As a start, the port uses the simplest possible configuration (no jemalloc, abort on panic) and makes use of existing Unix-specific code wherever possible.
It adds targets for x86_64 (current main HermitCore platform) and aarch64 (HermitCore platform under development).
Together with the patches to "liblibc" (https://github.com/rust-lang/libc/pull/1048) and llvm (https://github.com/rust-lang/llvm/pull/122), this enables HermitCore applications to be written in Rust.

Update clippy to latest master
r? @oli-obk
There is a regression in the version in current nightly that falsely lints `println!` and `writeln!` that use named arguments, thinking all rhs values for the argument expressions are literals even when they are not. This update includes the fix for that.
|
|
Previously these functions relied on TLS but we can instead thread the
relevant state through explicitly.

Removes dependency on UnstableFeatures from markdown rendering
|
|
Recent changes to lints disallowed lints from being emitted against code located
in foreign macros, except for future-incompatible lints. For a future
incompatible lint, however, the automatic suggestions may not be applicable!
This commit updates this code path to force all applicability suggestions made
to foreign macros to never be `MachineApplicable`. This should avoid rustfix
actually attempting fixing these suggestions, causing non-compiling code to be
produced.
Closes rust-lang/cargo#5799

Should hopefully bring in a few more `cargo fix`-related fixes.

Omit the vendor component in Fuchsia triple
Previously, using unknown as the vendor value would lead to the same
result, but with the multiarch runtimes support in Clang, the target is
now used to locate the runtime libraries and so the format is important.
The denormalized format with omitted vendor component is the format we
use with Clang and should be using for Rust as well.

Rollup of bare_trait_objects PRs
All deny attributes were moved into bootstrap so they can be disabled with a line of config.
Warnings for external tools are allowed and it's up to the tool's maintainer to keep it warnings free.

rustdoc: set panic output before starting compiler thread pool
When the compiler was updated to run on a thread pool, rustdoc's processing of compiler/doctest stderr/stdout was moved into each compiler thread. However, this caused output of the test to be lost if the test failed at *runtime* instead of compile time. This change sets up the `set_panic` call and output bomb before starting the compiler thread pool, so that the `Drop` call that writes back to the test's stdout happens after the test runs, not just after it compiles.
Fixes https://github.com/rust-lang/rust/issues/51162

overhaul exit codes for rustc and rustdoc
This commit changes the exit status of rustc to 1 in the presence of
compilation errors. In the event of an unexpected panic (ICE) the
standard panic error exit status of 101 remains.
A run-make test is added to ensure that the exit code does not regress,
and compiletest is updated to check for an exit status of 1 or 101,
depending on the mode and suite.
This is a breaking change for custom drivers.
Note that while changes were made to the rustdoc binary, there is no
intended behavior change. rustdoc errors (i.e., failed lints) will still
report 101. While this could *also* hide potential ICEs, I will leave
that work to a future PR.
Fixes #51971.

Preliminary work for incremental ThinLTO.
Since implementing incremental ThinLTO is a bit more involved than I initially thought, I'm splitting out some of the things that already work. This PR (1) adds a way accessing some ThinLTO information in `rustc` and (2) does some cleanup around CGU/object file naming (which makes things quite a bit nicer).
This is probably best reviewed one commit at a time.

make pretty source comparison check be fatal (fixes #52255)
This is not ready for merging because it reveals (at least) two regressions in the pretty suite. Should I attempt to fix those in this PR also?
