Add regression test for a gce + effects ICE
Fixes#125770
I'm not *exactly* sure why this stopped ICEing, I assume its something to do with the fact that there used to be a generic parameter on `Add` for the host generic and we have mismatched args here, which #125608 made no longer later cause issues. But now the desugaring is also different so? 🤷♀️

Remove lang feature for type ascription (since it's a lib feature now)
It's not necessary since it's a library feature now, via the type ascription macro. We can't (and shouldn't) register it as a removed feature since I think that would give "this feature has been removed" errors even for people using the macro (well, I'm pretty sure, though I didn't check).

Report usage of lib features in ast validation
No idea why it was split between ast validation for lang features and a later pass for lang features.

Fix `DebugParser`.
I tried using this and it didn't work at all. `prev_token` is never eof, so the accumulator is always false, which means the `then_some` always returns `None`, which means `scan` always returns `None`, and `tokens` always ends up an empty vec. I'm not sure how this code was supposed to work.
(An aside: I find `Iterator::scan` to be a pretty wretched function, that produces code which is very hard to understand. Probably why this is just one of two uses of it in the entire compiler.)
This commit changes it to a simpler imperative style that produces a valid `tokens` vec.

Merge Apple `std::os` extensions modules into `std::os::darwin`
The functionality available on Apple platforms are very similar, and were (basically) duplicated for each platform.
This PR rectifies that by merging the code into one module.
Ultimately, I've done this to fix `./x build library --target=aarch64-apple-tvos,aarch64-apple-watchos,aarch64-apple-visionos`, as that currently fails because of dead code warnings.
Publically exposing these to tvOS/watchOS/visionOS targets is considered in https://github.com/rust-lang/rust/pull/123723, but that seems to be dragging out, and in any case I think it makes sense to do the refactor separately from stabilization.
r? libs
Fixes https://github.com/rust-lang/rust/issues/121640 and https://github.com/rust-lang/rust/issues/124825.
The functionality available on Apple platforms are very similar, and
were duplicated for each platform.
Additionally, this fixes a warning when compiling the standard library
for tvOS, watchOS and visionOS by marking the corresponding code as
dead code.
Gate the type length limit check behind a nightly flag
Effectively disables the type length limit by introducing a `-Zenforce-type-length-limit` which defaults to **`false`**, since making the length limit actually be enforced ended up having a worse fallout than expected. We still keep the code around, but the type length limit attr is now a noop (except for its usage in some diagnostics code?).
r? `@lcnr` -- up to you to decide what team consensus we need here since this reverses an FCP decision.
Reopens#125460 (if we decide to reopen it or keep it closed)
Effectively reverses the decision FCP'd in #125507Closes#127346
