Migrate to LLVM{Get,Set}ValueName2
The deprecated `LLVM{Get,Set}ValueName` only work with NUL-terminated
strings, but the `2` variants use explicit lengths, which fits better
with Rust strings and slices. We now use these in new helper functions
`llvm::{get,set}_value_name` that convert to/from `&[u8]`.
Closes#64223.

SGX: Fix target linker used by bootstrap
Bootstrap, for some reason, overrides the target linker. This is not correct for x86_64-fortanix-unknown-sgx. Add such targets to the list of exceptions.

Remove potential cfgs duplicates
Fixes https://github.com/rust-lang/rust/issues/66921.
Before going any further (the issue seems to be linked to metadata as far as I can tell). Do you think this is the good place to do it or should it be done before?

Update the revision of wasi-libc used in wasm32-wasi
This commit updates the `wasi-libc` repository used to build the
wasm32-wasi target's libstd to ensure that both libstd and libc are
using the same wasi snapshot version.
Fix fetching arguments on the wasm32-wasi target
Fixes an error introduced in #66750 where wasi executables always think
they have zero arguments because one of the vectors returned here
accidentally thought it was length 0.
Add long error for E0631 and update ui tests.
This PR adds a long error for `E0631`, which covers errors where closure argument types are mismatched. It also updates UI tests where this error is applicable.
Part of #61137
[CI] fix the `! isCI` check in src/ci/run.sh
Using `if [ ! isCI ] || ...` doesn't run any command, just tests `isCI`
as a string, whereas `if ! isCI || ...` will actually run the `isCI`
command and negate its exit status.
std:win: avoid WSA_FLAG_NO_INHERIT flag and don't use SetHandleInformation on UWP
This flag is not supported on Windows 7 before SP1, and on windows server 2008 SP2. This breaks Socket creation & duplication.
This was fixed in a previous PR. cc #26658
This PR: cc #60260 reuses this flag to support UWP, and makes an attempt to handle the potential error.
This version still fails to create a socket, as the error returned by WSA on this case is WSAEINVAL (invalid argument). and not WSAEPROTOTYPE.

Make const-qualification look at more `const fn`s
As explained in a lot more detail in #67053 this makes const-qualification not ignore the unstable const fns in libcore.
r? @oli-obk cc @ecstatic-morse
(Still a bit unsure about the `cfg`s here, for bootstrapping, does that seem correct ?)
Fixes#67053.
Include a span in more `expected...found` notes
In most places, we use a span when emitting `expected...found` errors.
However, there were a couple of places where we didn't use any span,
resulting in hard-to-interpret error messages.
This commit attaches the relevant span to these notes, and additionally
switches over to using `note_expected_found` instead of manually
formatting the message
weak-into-raw: Clarify some details in Safety
Clarify it is OK to pass a pointer that never owned a weak count (one
from Weak::new) back into it as it was created from it. Relates to
discussion in #60728.
@CAD97 Do you want to have a look at the new docs?
Less minification
The goal of this PR is to remove the minification process on the `search-index.js` file. It provides great result in term of space reduction but the computation time is far too long. I'll work on this issue and will put it back once it's fast enough.

Reorganize borrow check diagnostic code
Currently borrow checker diagnostics are split across many different modules in different places in the `librustc_mir` crate. This moves them all to a `diagnostics` module. This also reduces the nesting of the modules a bit (sooo much nesting).
I am also thinking of moving stuff out of the `nll` module since we only have one borrow checker now (🎉), and maybe it even makes sense to split out all of this stuff to a `librustc_borrow_check`, but those are for the future. Feel free to ping me here or on zulip and let me know what you think...
