adapt issue-37945 codegen test to accept any order of ops
Adapt this test to accept `icmp` operands in any order as a follow-up to cbbf06b0cd (commitcomment-77670922).
bootstrap.py: Always use `.exe` for Windows
This ensures that it will run the Windows executable if other files in the directory (such as Linux executables) have the same file name minus the extension. I've been tripped up by this a few times where both `bootstrap` and `bootstrap.exe` end up in the same directory.
This PR avoids ever having to see the following message:
`OSError: [WinError 193] %1 is not a valid Win32 application`
`SessionDiagnostic` isn't suitable for use on lints as whether or not it
creates an error or a warning is decided at compile-time by the macro,
whereas lints decide this at runtime based on the location of the lint
being reported (as it will depend on the user's `allow`/`deny`
attributes, etc). Re-using most of the machinery for
`SessionDiagnostic`, this macro introduces a `LintDiagnostic` derive
which implements a `DecorateLint` trait, taking a
`LintDiagnosticBuilder` and adding to the lint according to the
diagnostic struct.
`sess` field of `SessionDiagnosticDeriveBuilder` is never actually used
in the builder's member functions, so it doesn't need to be a field.

Move the logic for building a field mapping (which is used by the
building of format strings in `suggestion` annotations) into a helper
function.

Remove FIXME from rustdoc intra-doc test
Removed the FIXME.
For the `extern crate`, even if `pub` exported, its documentation wasn't rendered so there is no point in keeping it.

rustdoc: improve click behavior of the source code mobile full-screen "sidebar"
On desktop, if you open the source code sidebar, it stays open even when you move from page to page. It used to do the same thing on mobile, but I think that's stupid. Since the file list fills the entire screen on mobile, and you can't really do anything with the currently selected file other than dismiss the "sidebar" to look at it, it's safe to assume that anybody who clicks a file in that list probably wants the list to go away so they can see it.

lints: mostly translatable diagnostics
As lints are created slightly differently than other diagnostics, intended to try make them translatable first and then look into the applicability of diagnostic structs but ended up just making most of the diagnostics in the crate translatable (which will still be useful if I do make a lot of them structs later anyway).

ptr::copy and ptr::swap are doing untyped copies
The consensus in https://github.com/rust-lang/rust/issues/63159 seemed to be that these operations should be "untyped", i.e., they should treat the data as raw bytes, should work when these bytes violate the validity invariant of `T`, and should exactly preserve the initialization state of the bytes that are being copied. This is already somewhat implied by the description of "copying/swapping size*N bytes" (rather than "N instances of `T`").
The implementations mostly already work that way (well, for LLVM's intrinsics the documentation is not precise enough to say what exactly happens to poison, but if this ever gets clarified to something that would *not* perfectly preserve poison, then I strongly assume there will be some way to make a copy that *does* perfectly preserve poison). However, I had to adjust `swap_nonoverlapping`; after ``@scottmcm's`` [recent changes](https://github.com/rust-lang/rust/pull/94212), that one (sometimes) made a typed copy. (Note that `mem::swap`, which works on mutable references, is unchanged. It is documented as "swapping the values at two mutable locations", which to me strongly indicates that it is indeed typed. It is also safe and can rely on `&mut T` pointing to a valid `T` as part of its safety invariant.)
On top of adding a test (that will be run by Miri), this PR then also adjusts the documentation to indeed stably promise the untyped semantics. I assume this means the PR has to go through t-libs (and maybe t-lang?) FCP.
Fixes https://github.com/rust-lang/rust/issues/63159
Change enum->int casts to not go through MIR casts.
follow-up to https://github.com/rust-lang/rust/pull/96814
this simplifies all backends and even gives LLVM more information about the return value of `Rvalue::Discriminant`, enabling optimizations in more cases.
clean up the borrowing in rustc_hir_pretty
A whole lot of the `&`s and `ref`s were redundant. I hope doing this in one big commit is fine, because all of the changes are pretty self-contained.
