Update to LLVM 17.0.6
This is a rebase on the final LLVM 17 release.
Includes the RISCV fix requested in https://github.com/rust-lang/llvm-project/pull/157 (and I think this is also the only change in this release that is relevant to rustc).

Fixes#117902
There are a number of fixes here:
* if-unchanged is supposed to be the default for channel=dev, but
actually used different logic. Make sure it is the same.
* If no llvm section was specified at all, different logic was
also used. Go through the standard helper.
* Some more assertions should depend on if_unchanged.

To ensure deterministic results we must sort the dump lines.
This is necessary because the order of rustc invocations different
almost all the time.

When making changes to the bootstrap that shouldn't change its behavior,
this feature will help developers perform comparisons to check whether the
bootstrap behavior has changed or not.
This can also be used for different purposes. For example, allowing CI to
dump the shims and upload them so that developers can download them and compare
with their local dump to see if CI affects the bootstrap unexpectedly. Or, make CI
perform comparisons on specific bootstrap tests to check for behavior changes between
the master and PR branches.

This reverts commit 40c3d351ad. The option was dogfooded for using lld with MCP510 , but it broke testing with LLD, because we don't pass `-Zunstable-options` on enough places.

As bootstrap locks its entire build directory, parallel bootstrapping
for anything becomes impossible. This change enables developers to bypass
the locking mechanism when it is unnecessary for their specific use case.

Build Fuchsia in CI
Fittingly, when I first put this up it was failing due to discovering an ICE in clippy (looks like fixed in https://github.com/rust-lang/rust-clippy/pull/11760), probably more fallout from recent type system changes. Other recent regressions this would have caught include
- #117455 and #117493
- #117602
Originally we discussed basing this on cargotest, but they ended up not sharing anything. Fuchsia has its own tool to manage checkouts and its own build system. What it requires is a fully "install"ed toolchain with a host and fuchsia target. We share logic from the dist-various-2 builder to build the fuchsia target.
Right now this runs clippy and skips linking a bunch of targets, since most issues we catch are in the frontend. In theory we could probably get the build CPU time down quite a bit with this approach, but right now some linked targets are creeping into the dependencies anyway and we don't have a good way of preventing that yet.
The approach is basically to get a checkout at a pinned commit and then run a [script](https://fuchsia-review.git.corp.google.com/c/fuchsia/+/943833/6/scripts/rust/build_fuchsia_from_rust_ci.sh) at a predetermined location. I would like to update that pin every few weeks. Partial checkouts are used to minimize clone time, but we don't filter out prebuilt packages.
r? `@Mark-Simulacrum`
Based on discussion in [this Zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/242791-t-infra/topic/Putting.20Fuchsia.20in.20crater).
Remove extra check cfg handled by libc directly
The `libc` crate has handle for quite some time now [check-cfg in it's own build script](497ac428bc/build.rs (L6-L32)).
We therefor no longer need to manually define them.
add safe compilation options
Add two options when building rustc : strip and stack protector.
If set `strip = true`, `rustc` will be stripped of symbols using `-Cstrip=symbols`.
Also can set `stack-protector` and then `rustc` will be compiled with stack protectors.
add comment about keeping flags in sync between bootstrap.py and bootstrap.rs
They got out of sync, probably because this comment was missing on the Python side (it only exists on the Rust side). https://github.com/rust-lang/rust/pull/118642 brings the flags back in sync but does not fix the comment, so let's do that here.

bootstrap(builder.rs): Don't explicitly warn against `semicolon_in_expressions_from_macros`
This already wasn't passed in bootstrap.py and the lint itself already warns-by-default for 2 years now and has already been added to the future-incompat group in Rust 1.68.
See https://github.com/rust-lang/rust/issues/79813 for the tracking issue.

utilize stdlib debug assertion status in compiletest
Implemented a new flag `--with-debug-assertions` on compiletest to pass the stdlib debug assertion status from bootstrap.

give dev-friendly error message for incorrect config profiles
before this change, an incorrect profile would result in the following error:

bootstrap: Memoize the LLVM rebuild hash to avoid very slow `x check`
Recently I've encountered a massive regression in the performance of re-running `x check` after making no changes.
It used to take around 2 seconds, and now it takes 20-30 seconds. That's quite a hassle when r-a runs it every time I save.
After some poking around, what I've found is that each individual call to `generate_smart_stamp_hash` doesn't take a particularly long time (around 0.5 sec), but it gets called dozens of times during `x check`, and that seems to be what's adding up to 20-30 seconds.

skip {tidy,compiletest,rustdoc-gui} based tests for `DocTests::Only`
As use of `--doc` with `x test` is intended for running doc-tests only, executing compiletest, tidy or rustdoc-gui based tests considered as an incorrect behavior from bootstrap. This change fixes that.
