tweaks to retag diagnostic handling

Salvaged from rust-lang#106212

Rustup

This reverts commit 9dfe504.

Fixes `x clippy`.

When this happens, we ignore the symbol from `compiler_builtins`
in favor of Miri's builtin support.

This allows Miri to target platforms like wasm32-unknown-unknown,
where functions like `memcmp` are provided by `compiler_builtins`.

Ignore symbol shim clash when symbol is provided by compiler_builtins

in favor of Miri's builtin support.

…lfJung

add dtors_in_dtors_in_dtors

That's a pretty neat test from the standard library. Sadly not enough to check for rust-lang/miri#2754, but still worth having here.

Because the old spelling is widely used, some projects may need time to
migrate their uses to the new triple spelling. The old spelling may
eventually be removed altogether.

…flatten_doc, r=cuviper

Add example for iterator_flatten

Adds an Example to iterator_flatten
Fixes rust-lang#82687

…agisa

Enable atomic cas for bpf targets

It seems like LLVM now supports it.

https://reviews.llvm.org/D72184 - the PR in LLVM

…=oli-obk

Fix bad import suggestion with nested `use` tree

Fixes rust-lang#105566
Fixes rust-lang#105373

Ideally, we'd find some way to turn these into structured suggestions -- perhaps on a separate line as a different `use` statement, but I have no idea how to access the span for the whole `use` from this point in the import resolution code.

…-compare, r=oli-obk

No need to take opaques in `check_type_bounds`

`InferCtxt` already has its defining use anchor set to err

r? ``@oli-obk``

Revert "bootstrap: Get rid of `tail_args` in `stream_cargo`"

This reverts commit 9dfe504. (Note: that merged as part of rust-lang#106305, but rust-lang#106305 contains more commits than just 9dfe504.)

Fixes `x clippy`. It turns out `clippy` was the only one using `tail_args` 🤦 sorry for not testing this earlier.

r? `@Mark-Simulacrum`

Accept old spelling of Fuchsia target triples

The old spelling of Fuchsia target triples was changed in rust-lang#106429 to add a proper vendor. Because the old spelling is widely used, some projects may need time to migrate their uses to the new triple spelling. The old spelling may eventually be removed altogether.

r? ``@tmandry``

r? `@ghost`

update test for inductive canonical cycles

the previous test always resulted in a cycle 😅 cc rust-lang/chalk#787.

I checked with rust-lang#102713 and this is the only test which fails with that PR.
