Previously, we were trying to install all doc files under "share/doc/rust"
which caused `rust-installer` tool to create backup files (*.old) due to filename
conflicts. With this change, doc files is now installed under "share/doc/{package}",
where {package} could be rustc, cargo, clippy, etc.

Previously, we used the entire sysroot binary path to prepare rustc tarballs.
Since we also copy tool binaries to the sysroot binary path, installing rustc
and tools with `x install` results in attempting to install the same binaries
more than once. This causes rust-installer to create backup files (*.old) due
to file conflicts. This change fixes that.

This change helps us to bypass downloading the beta compiler in bootstrap tests.

Subdiagnostics don't need to be lazily translated, they can always be
eagerly translated. Eager translation is slightly more complex as we need
to have a `DiagCtxt` available to perform the translation, which involves
slightly more threading of that context.

This slight increase in complexity should enable later simplifications -
like passing `DiagCtxt` into `AddToDiagnostic` and moving Fluent messages
into the diagnostic structs rather than having them in separate files
(working on that was what led to this change).

Because they all are, in practice.
i386-apple-ios is also a simulator target
Due to missing stamp file, we were downloading (and applying nix patches if enabled)
continuously every time `Config::download_clippy` was called. This change fixes that by
creating stamp file at the end of the function.

Don't use mem::zeroed in vec::IntoIter

`mem::zeroed` is not a trivial function. Maybe it was once, but now it involves multiple locals, copies, and an intrinsic that gets monomorphized into a call to `panic_nounwind` for iterators of types like `Vec<&T>`. Of course all that complexity is trivially optimized out, but generating a bunch of IR where we don't need to just so we can optimize it away later is silly.

distribute tool documentations and avoid file conflicts on `x install`

I suggest reading commits one-by-one with the descriptions for more context about the changes.

errors: only eagerly translate subdiagnostics

Subdiagnostics don't need to be lazily translated, they can always be eagerly translated. Eager translation is slightly more complex as we need to have a `DiagCtxt` available to perform the translation, which involves slightly more threading of that context.

This slight increase in complexity should enable later simplifications - like passing `DiagCtxt` into `AddToDiagnostic` and moving Fluent messages into the diagnostic structs rather than having them in separate files (working on that was what led to this change).

This change helps us to bypass downloading the beta compiler in bootstrap tests.

…ent, r=lcnr

Use fulfillment in next trait solver coherence

Use fulfillment in the new trait solver's `impl_intersection_has_impossible_obligation` routine. This means that inference that falls out of processing other obligations can influence whether we can determine if an obligation is impossible to satisfy. See the committed test.

This should be completely sound, since evaluation and fulfillment both respect intercrate mode equally.

We run the risk of breaking coherence later if we were to change the rules of fulfillment and/or inference during coherence, but this is a problem which affects evaluation, as nested obligations from a trait goal are processed together and can influence each other in the same way.

r? lcnr
cc rust-lang#114862

Also changed obligationctxt -> fulfillmentctxt because it feels kind of redundant to use an ocx here. I don't really care enough and can change it back if it really matters much.

Fix `cfg(target_abi = "sim")` on `i386-apple-ios`

Since rust-lang#80970 is stabilizing, I went and had a look, and found that the result was wrong on `i386-apple-ios`.
