bootstrap: drop warning for top-level test suite path check due to false positives
The current top-level test suite directory does not exist warning logic doesn't quite handle the more exotic path suffix matches that test filters seem to accept (e.g. `library/test` can be matched with `--exclude test`), so avoid warning on non-existent top-level test suites for now. To avoid false positives, we probably need to query test `Step`s for their `should_run(exclude_filter)` logic.
This retains the fix for the Windows path handling (unlike #134843).

Since 9cb1998ea15e179482504e07cad8fa121e169a32 this feature is viral.

replace bootstrap-self-test feature flag with cfg(test)
This makes it in more rusty way.

There are no tests in `tests/debuginfo` that use this prefix.

This doesn't quite handle the more exotic path suffix matches that test
filters seem to accept (e.g. `library/test` can be matched with
`--exclude test`), so avoid warning on non-existent top-level test
suites for now. A proper fix will need to possibly query test `Step`s
for their exclude logic.

compiletest: Only pass the post-colon value to `parse_normalize_rule`
Addresses one of the FIXMEs noted in #134759.
I started working on the other FIXME, but it became complex enough that I wanted to split it off from this PR.

Migrate `libs-through-symlink` to rmake.rs
Part of https://github.com/rust-lang/rust/issues/121876.
This PR migrates `tests/run-make/libs-through-symlink/` to use rmake.rs.
- Regression test for #13890.
- Original fix PR is #13903.
- Document test intent, backlink to #13890 and fix PR #13903.
- Fix the test logic: the `Makefile` version seems to not actually be exercising the "library search traverses symlink" logic, because the actual symlinked-to-library is present under the `$(TMPDIR)` directory tree when `bar.rs` is compiled, because the `$(RUSTC)` invocation has an implicit `-L $(TMPDIR)`. The symlink itself was actually broken, i.e. it should've been `ln -nsf $(TMPDIR)/outdir/$(NAME) $(TMPDIR)` but it used `ln -nsf outdir/$(NAME) $(TMPDIR)`. The rmake.rs version now explicitly separates the two directory trees and sets the CWD of the `bar.rs` rustc invocation so that the actual library is *not* present under its CWD tree.
I.e. it is now
```
$test_output/ # rustc foo.rs -o actual_lib_dir/libfoo.rlib
actual_lib_dir/
libfoo.rlib
symlink_lib_dir/ # CWD set; rustc -L . bar.rs
libfoo.rlib --> $test_output/actual_lib_dir/libfoo.rlib
```
Partially supersedes #129011.

- The Makefile version *never* ran because of Makefile syntax confusion.
- The test would've always failed because precompiled std is not built
with `-Z cf-protection=branch`, but linkers require all input object
files to indicate IBT support in order to enable IBT for the
executable, which is not the case for std.
- Thus, the test input file is instead changed to a `no_std` + `no_core`
program.

The old FIXME implies that we don't support escaped newlines, but in fact it
was added in the same patch that added support for escaped newlines.
The new FIXME makes it clear that we do currently support this, and that the
FIXME is for doing so in a less ad-hoc way.

CI: Add LTO support to clang in dist-x86_64-linux
After https://github.com/rust-lang/cc-rs/pull/1279, we attempt to pass `-flto=thin` to clang. In `dist-x86_64-linux`, we don't build clang with the `LLVMgold.so` library so this fails. This attempts to resolve this
First, pass the binutils plugin include directory to Clang, [which will build the library](https://github.com/llvm/llvm-project/blob/2d6d723a85c2d007b0359c206d66cd2e5a9f00e1/llvm/docs/GoldPlugin.rst#how-to-build-it)
Second, this library depends on the *version of libstdc++ that we built* specifically. However, despite both the RPATH and LD_LIBRARY_PATH pointing to `/rustroot/lib`, we incorrectly resolve to the system libstdc++, which doesn't load.
```
# LD_DEBUG=libs,files
2219: file=libstdc++.so.6 [0]; needed by /rustroot/bin/../lib/LLVMgold.so [0]
2219: find library=libstdc++.so.6 [0]; searching
2219: search path=/rustroot/bin/../lib/../lib (RPATH from file /rustroot/bin/../lib/LLVMgold.so)
2219: trying file=/rustroot/bin/../lib/../lib/libstdc++.so.6
2219: search path=/usr/lib64/tls:/usr/lib64 (system search path)
2219: trying file=/usr/lib64/tls/libstdc++.so.6
2219: trying file=/usr/lib64/libstdc++.so.6
```
Using `LD_PRELOAD` causes it to correctly load the library
I think this is probably not the most maintainable way to do this, so opening to see if this is desired and if there's a better way of doing this

Add `--no-capture`/`--nocapture` as bootstrap arguments
I often try `x test ... --nocapture` => 'unknown argument' => `x test ... -- --nocapture`. As we forward several other compiletest flags, let's recognise this one in bootstrap as well.

compiletest: Remove empty 'expected' files when blessing
Fixes #134793
Fixes #134196
This also refactors `compare_output` to return an enum; returning a usize was done for convenience but is misleading

Sort triples by name in platform_support.md
When looking for riscv32emc support, I missed it at first because it was at the end of the tier3 target list [here](https://doc.rust-lang.org/rustc/platform-support.html#tier-3). These lists are *mostly* dictionary sorted so I assumed it should be near the riscv32i* targets.
This PR puts all targets back in dictionary order. There were only a few outside of tier3.
I ended up writing a small program to sort them because I did not trust myself to do it manually, but I stopped short of fully automating it.
I have manually reviewed the output to confirm it still has the same number of entries, and that the changed values do follow the ordering I would expect.
For folks who would prefer to review code than manual textual changes, the sorting program (including inputs) is [here.](https://github.com/9names/platform_sort_arch/blob/main/src/main.rs)

rustdoc: use shorter paths as preferred canonical paths
This is a solution to [the `std::sync::poison` linking problem](https://github.com/rust-lang/rust/pull/134692#issuecomment-2560373308), and, in general, makes intra-doc links shorter and clearer.
> Done. This helped with the search, but not with the things like `MutexGuard`'s doc's reference to `Mutex::lock` being converted to the absolute (unstable) `std::sync::poison::Mutex` path.
