c48cdfe8ee Remove unnecessary lets and borrowing from Waker::noop() usage. 
`Waker::noop()` now returns a `&'static Waker` reference, so it can be
passed directly to `Context` creation with no temporary lifetime issue.

Rollup merge of #119563 - compiler-errors:coroutine-resume, r=oli-obk 
Check yield terminator's resume type in borrowck

In borrowck, we didn't check that the lifetimes of the `TerminatorKind::Yield`'s `resume_place` were actually compatible with the coroutine's signature. That means that the lifetimes were totally going unchecked. Whoops!

This PR implements this checking.

Fixes #119564

5113ed28ea Auto merge of #118297 - shepmaster:warn-dead-tuple-fields, r=WaffleLapkin 
Merge `unused_tuple_struct_fields` into `dead_code`

This implicitly upgrades the lint from `allow` to `warn` and places it into the `unused` lint group.

Rollup merge of #118871 - tmiasko:coroutine-maybe-uninit-fields, r=compiler-errors 
Coroutine variant fields can be uninitialized

Wrap coroutine variant fields in MaybeUninit to indicate that they might be uninitialized. Otherwise an uninhabited field will make the entire variant uninhabited and introduce undefined behaviour.

The analogous issue in the prefix of coroutine layout was addressed by 6fae7f8071.

5161b22143 Fix coroutine validation for mixed panic strategy 
Validation introduced in #113124 allows UnwindAction::Continue and
TerminatorKind::Resume to occur only in functions with ABI that can
unwind. The function ABI depends on the panic strategy, which can vary
across crates.

Usually MIR is built and validated in the same crate. The coroutine drop
glue thus far was an exception. As a result validation could fail when
mixing different panic strategies.

Avoid the problem by executing AbortUnwindingCalls along with the
validation.

Rollup merge of #117338 - workingjubilee:asmjs-meets-thanatos, r=b-naber 
Remove asmjs

Fulfills [MCP 668](https://github.com/rust-lang/compiler-team/issues/668).

`asmjs-unknown-emscripten` does not work as-specified, and lacks essential upstream support for generating asm.js, so it should not exist at all.
