Always install when the build succeeds

Fix caching issue when building tools.
This fixes a problem with tool builds not being cached properly.
#73297 changed it so that Clippy will participate in the "deny warnings" setting. Unfortunately this causes a problem because Clippy shares the build directory with other tools which do not participate in "deny warnings". Because Cargo does not independently cache artifacts based on different RUSTFLAGS settings, it causes all the shared dependencies to get rebuilt if Clippy ever gets built.
The solution here is to stop using RUSTFLAGS, and just sneak the settings in through the rustc wrapper. Cargo won't know about the different settings, so it will not bust the cache. This should be safe since lint settings on dependencies are ignored. This is how things used to work in the past before #64316.
Alternate solutions:
* Treat Clippy as a "submodule" and don't enforce warnings on it. This was the behavior before #73297. The consequence is that if a warning sneaks into clippy, that the clippy maintainers will need to fix it when they sync clippy back to the clippy repo.
* Just deny warnings on all tools (removing the in-tree/submodule distinction). This is tempting, but with some issues (cc #52336):
* Adding or changing warnings in rustc can be difficult to land because tools have to be updated if they trip the warning. In practice, this isn't too bad. Cargo (and rustfmt) already runs with `deny(warnings)`, so this has been the de-facto standard already (although they do not use the extra lints like `unused_lifetimes`).
* Teach Cargo to add flags to the workspace members, but not dependencies.
* Teach Cargo to add flags without fingerprinting them?
* Teach Cargo to independently cache different RUSTFLAGS artifacts (this was [reverted](https://github.com/rust-lang/cargo/pull/7417) due to complications). This would also unnecessarily rebuild dependencies, but would avoid cache thrashing.
* Teach Cargo about lint settings.
Closes #74016

Fix cross compilation of LLVM to aarch64 Windows targets
When cross-compiling, the LLVM build system recurses to build tools that need to run on the host system. However, since we pass cmake defines to set the compiler and target, LLVM still compiles these tools for the target system, rather than the host. The tools then fail to execute during the LLVM build.
This change sets defines for the tools that need to run on the host (llvm-nm, llvm-tablegen, and llvm-config), so that the LLVM build does not attempt to build them, and instead relies on the tools already built.
If compiling with clang-cl, adds the `--target` option to specify the target triple. MSVC compilers do not require this, since there is a separate compiler binary for each cross-compilation target.
Related issue: #72881
Requires LLVM change: rust-lang/llvm-project#67

This commit replaces the use of `trim_start_matches`
because in `rustc -Vv` output there are no lines
starting with multiple "release:".

Remove unused RUSTC_DEBUG_ASSERTIONS
Since #73374 the rustc wrapper no longer configures debug assertions
based on RUSTC_DEBUG_ASSERTIONS environment variable.

[rustdoc] Page hash handling
Fixes https://github.com/rust-lang/rust/issues/70476
A good example to see the change is to use this URL: https://doc.rust-lang.org/nightly/std/string/struct.String.html#from_iter.v-3
After the change, it actually goes to the target element (and change the page hash to something more clear for the users).

The current plan is that submodule tracks the `release` branch of
rust-analyzer, which is updated once a week.
rust-analyzer is a workspace (with a virtual manifest), the actual
binary is provide by `crates/rust-analyzer` package.
Note that we intentionally don't add rust-analyzer to `Kind::Test`,
for two reasons.
*First*, at the moment rust-analyzer's test suite does a couple of
things which might not work in the context of rust repository. For
example, it shells out directly to `rustup` and `rustfmt`. So, making
this work requires non-trivial efforts.
*Second*, it seems unlikely that running tests in rust-lang/rust repo
would provide any additional guarantees. rust-analyzer builds with
stable and does not depend on the specifics of the compiler, so
changes to compiler can't break ra, unless they break stability
guarantee. Additionally, rust-analyzer itself is gated on bors, so we
are pretty confident that test suite passes.

Changes required for rustc/cargo to build for iOS targets

NOTE: cargo required arm64-ios openssl/libcurl to be linked.

Compile rustdoc less often.
Previously rustdoc was built 3 times with `x.py test`:
1. stage2 (using stage1 compiler) for compiletest tests (stage1-tools copied to stage2).
2. stage1 (using stage0 compiler) for std crate tests (stage0-tools copied to stage1).
3. stage2 test (using stage2 compiler) for rustdoc crate tests and error_index_generator (stage2-tools).
This PR removes the majority of number 3, where it will instead use the stage1 compiler, which will share the artifacts from number 1.
This matches the behavior of the libstd crate tests. I don't think it is entirely necessary to run the tests using stage2.
At `-j2`, the last build step goes from about 300s to 70s on my machine. It's not a huge win, but shaving 4 minutes isn't bad.
The other two builds would be pretty difficult (or undesired or impossible) to unify. It looks like std tests use stage1 very intentionally (see `force_use_stage1` and its history), and compiletests use the top stage very intentionally.
Unfortunately the linkchecker builds all docs at stage2 (stage2-tools), which means a few build script artifacts are not shared. It's not really clear to me how to fix that (because it uses `default_doc`, there doesn't seem to be any control over the stages).
---
For `x.py doc`, rustdoc was previously built three times (with compiler-docs):
1. stage2 (using stage1 compiler) for normal documentation output (stage1-tools copied to stage2).
2. stage1 (using stage0 compiler) for compiler-docs
3. stage2 (using stage2 compiler) for error_index_generator (stage2-tools)
This PR combines these so that they consistently use the "top stage" rustdoc. I don't know why the compiler-docs was written to use stage minus one, but it seems better to be consistent across the doc steps.
---
I've tried to test this with a variety of commands (`x.py doc`, `x.py test`, different `--stage` flags, `full-bootstrap`, setting `--target`, etc.) to try to make sure there aren't significant regressions here. It's tricky since there are so many variables, and this stuff is difficult for me to fully understand.
Closes #70799 (I think)

Remove legacy InnoSetup GUI installer
On Windows the InnoSetup `.exe` installer was superseded by the MSI installer long ago. It's no longer needed.
The `.exe` installer hasn't been linked from the [other installation methods](https://forge.rust-lang.org/infra/other-installation-methods.html#standalone) page in many years. As far as I can tell the intent was always to remove this installer once the MSI proved itself. Though admittedly both installers feel very "legacy" at this point.
Removing this would mean we only maintain one Windows GUI installer and would speed up the distribution phase.
As a result of removing InnoSetup, this closes #24397

rustbuild: Move compiler-builtins build logic to manifest
This commit moves the compiler-builtins-specific build logic from
`src/bootstrap/bin/rustc.rs` into the workspace `Cargo.toml`'s
`[profile]` configuration. Now that rust-lang/cargo#7253 is fixed we can
ensure that Cargo knows about debug assertions settings, and it can also
be configured to specifically disable debug assertions unconditionally
for compiler-builtins. This should improve rebuild logic when
debug-assertions settings change and also improve build-std integration
where Cargo externally now has an avenue to learn how to build
compiler-builtins as well.

Update mdbook
This updates mdbook to 0.4. The list of changes can be found at https://github.com/rust-lang/mdBook/blob/master/CHANGELOG.md#mdbook-040. I think the most important one is the change to include fonts with the book instead of using the Google Fonts CDN. This adds a few megabytes of fonts to the docs component. It may be possible to share the fonts across the books, but would take a fair bit of work to make that happen, so I'm not sure if it is necessary.
This also removes mdbook-linkcheck. It is currently not being used, and I don't foresee it going back into use anytime soon. I would prefer not to maintain something that isn't being used, and it removes a very large number of dependencies.

Fortanix SGX target libunwind build process changes
Ticket: https://github.com/fortanix/rust-sgx/issues/174
LLVM related changes (merged): https://github.com/rust-lang/llvm-project/pull/57
Description: libunwind changes needed to run code in sgx environment via rust-sgx.
Target that uses this in rust: x86_64-fortanix-unknown-sgx.
Without this change, rust std for this toolchain is forced to use a precompiled library loaded via environment variable.
With this change we act the same as musl target.

Enable LLVM zlib
Compilers may generate ELF objects with compressed sections (although rustc currently doesn't do this). Currently, when linking these with `rust-lld`, you'll get this error:
`rust-lld: error: ...: contains a compressed section, but zlib is not available`
This enables zlib when building LLVM.

Speed up bootstrap a little.
The bootstrap script was calling `cargo metadata` 3 times (or 6 with `-v`). This is a very expensive operation, and this attempts to avoid the extra calls. On my system, a simple command like `./x.py test -h -v` goes from about 3 seconds to 0.4.
An overview of the changes:
- Call `cargo metadata` only once with `--no-deps`. Optional dependencies are filtered in `in_tree_crates` (handling `profiler_builtins` and `rustc_codegen_llvm` which are driven by the config).
- Remove a duplicate call to `metadata::build` when using `-v`. I'm not sure why it was there, it looks like a mistake or vestigial from previous behavior.
- Remove check for `_shim`, I believe all the `_shim` crates are now gone.
- Remove check for `rustc_` and `*san` for `test::Crate::should_run`, these are no longer dependencies in the `test` tree.
- Use relative paths in `./x.py test -h -v` output.
- Some code cleanup (remove unnecessary `find_compiler_crates`, etc.).
- Show suite paths (`src/test/ui/...`) in `./x.py test -h -v` output.
- Some doc comments.
