This fixes an issue where the C and asm sources built by
compiler_builtins were being compiled as ELF objects instead of PE
objects. This wasn't noticed before because it doesn't cause
compiler_builtins or rustc to fail to build. You only see a failure when
a program is built that references one of the symbols in an ELF object.
Compiling with clang fixes this because the `cc` crate converts the UEFI
targets into Windows targets that clang understands, causing it to
produce PE objects.
Note that this requires compiler_builtins >= 0.1.84.

Enable profiler in dist-s390x-linux
Build the profiler runtime to allow using -C profile-generate and -C instrument-coverage on s390x-linux.
I've verified in a local build that the runtime builds and the profiler is working fine on the platform.
ci: Upgrade dist-x86_64-netbsd to NetBSD 9.0
This is another step in toolchain upgrades for LLVM 16, which will need at least GCC 7.1.
Our previous NetBSD 8.0 cross-toolchain used its system GCC 5.5. While there are newer versions available in pkgsrc, I could not get those working for cross-compilation. Upgrading to NetBSD 9.0 gets us GCC 7.4, which is sufficient for now.
This will affect the compatibility of the build we ship for `x86_64-unknown-netbsd`, but others may still build their own from source if that is needed. It is expected that NetBSD 8 will reach EOL soon anyway, approximately one month after 10 is released, but there is no firm date for that.

Reduce default configuration's dependency upon static libstdcpp library (#103606)
Fixes#103606
Remove default dependency on static libstdcpp except during dist llvm builds (where we want static libraries so `libLLVM.so` is self-contained).
Usually, we do want to use the static C++ library when building rustc_llvm, but do not want to have that dependency at compiler runtime. Change the defaults to Make It So.
Add check in GUI test for file loading failure
Since https://github.com/rust-lang/rust/pull/101702, some resources location need to be updated in case their content changed because then their hash will change too. This will prevent errors like https://github.com/rust-lang/rust/pull/104114 to happen again.
The second commit is to prevent CORS errors: when a file is linked from a file itself imported, the web browser considers they come from a different domain and therefore triggers the error. The option tells the web browser to ignore this case.

Add QEMU test for x86_64-unknown-uefi
The UEFI targets don't have std support yet, so the normal tests don't work. However, we can compile a simple no-std program and run it under QEMU to at least check that the target compiles, links, and runs.
Tested locally with: `src/ci/docker/run.sh x86_64-uefi`
ci: Bring back ninja for dist builders
The primary reason for this is that make can result in a substantial under utilization of parallelism (noticed while testing on a workstation), mostly due to the submake structure preventing good dependency tracking and scheduling.
In f758c7b2a7 (Debian 6 doesn't have ninja, so use make for the dist builds) llvm.ninja was disabled due to lack of distro package. This is no longer the case with the CentOS 7 base, so bring ninja back for a performance boost.
This reverts commit 3acb505ee5
(PR #101833).
The changes in this commit caused several bugs or at least
incompatibilies. For now we're reverting this commit and will re-land it
alongside fixes for those bugs.
update Miri
I had to use a hacked version of josh to create this, so let's be careful with merging this and maybe wait a bit to see if the josh issue becomes more clear. But the history looks good to me, we are not adding duplicates of rustc commits that were previously mirrored to Miri.
Also I want to add some cross-testing of Miri in x.py.
Upgrade dist-mips*-linux to ubuntu:22.04 + crosstool-ng
These have no change in compatibility, still Linux 4.4 and glibc 2.23.
The main motivation for upgrading is that LLVM 16 will require at least GCC 7.1. Using crosstool-ng lets us choose our own toolchain versions, and then the Ubuntu version doesn't matter so much, just for the host compilation while we cross-compile.
The primary reason for this is that make can result in a substantial
under utilization of parallelism, mostly due to the submake structure

Improve rustdoc-gui search-color test
Thanks to the add of "functions" in `browser-ui-test`, we can start to reduce the size of the scripts. It'll be very useful for all color checks.

Use BOLT in CI to optimize LLVM
This PR adds an optimization step in the Linux `dist` CI pipeline that uses [BOLT](https://github.com/llvm/llvm-project/tree/main/bolt) to optimize the `libLLVM.so` library built by boostrap.
Steps:
- [x] Use LLVM 15 as a bootstrap compiler and use it to build BOLT
- [x] Compile LLVM with support for relocations (`-DCMAKE_SHARED_LINKER_FLAGS="-Wl,-q"`)
- [x] Gather profile data using instrumented LLVM
- [x] Apply profile to LLVM that has already been PGOfied
- [x] Run with BOLT profiling on more benchmarks
- [x] Decide on the order of optimization (PGO -> BOLT?)
- [x] Decide how we should get `bolt` (currently we use the host `bolt`)
- [x] Clean up
The latest perf results can be found [here](https://github.com/rust-lang/rust/pull/94381#issuecomment-1258269440). The current CI build time with BOLT applied is around 1h 55 minutes.
Update CI to use Android NDK r25b
This commit updates the CI definitions to use the most recent Android LTS NDK release: r25b. Changes since the last NDK used by Rust negate the need to generate "standalone toolchains" and newer NDKs can be used in-place.

Update browser UI test version
It added the possibility to concatenate strings and numbers and updated the `goto` command so it doesn't stand on its own anymore.
r? ````@notriddle````
Compressed debug is enabled by default for gas (assembly) on Linux/x86
targets, and we started building our own in #102530, but that made our
`compiler_builtins` incompatible with binutils < 2.32. Add an explicit
option to disable that in our crosstool-ng config. Fixes#102703.
Miri sync
This is a Miri sync created with my experimental fork of josh. We should probably not merge this yet, but we can use this to check if the sync looks the way it should.
