Tweak type flags, fix missing flags from coroutine kind ty
Firstly, make sure we visit the coroutine kind ty. Since this kind ty is either infer (before upvar computation), or `()` or `i8`/`i16`/`i32`, this isn't really that big of a deal, since other types in the coroutine will also be infer, so we're not misreporting `ty.has_infer()` or anything, but it's still wrong not to do this.
Furthermore, remove `HAS_TY_COROUTINE`, since nobody used it, and also remove special casing for `STILL_FURTHER_SPECIALIZABLE` since it's likely not important anymore? I have a vague recollection that it was important for polymorphization(?), but no tests seem to rely on this behavior.
r? lcnr or reassign
Say which test failed the `COMPILETEST_REQUIRE_ALL_LLVM_COMPONENTS` assertion
Closes#138857.
This is of course a spot fix. The general problem requires reworking compiletest directive handling's diagnostics logic.
std: uefi: fs: Implement mkdir
- Since there is no direct mkdir in UEFI, first check if a file/dir with same path exists and then create the directory.

Add unstable `--print=supported-crate-types` option
MCP: https://github.com/rust-lang/compiler-team/issues/836
Tracking issue: https://github.com/rust-lang/rust/issues/138640
### Test coverage
Two tests:
1. `tests/ui/print-request/stability.rs` to check that `--print=supported-crate-types` is `-Zunstable-options`-gated
2. `tests/ui/print-request/supported-crate-types.rs` is added as a basic smoke test. Observe that the compiler stdout corresponds to the below *Example output* section (e.g. `proc-macro` is unsupported on `wasm32-unknown-unknown` currently).
### Example output
<details>
<summary>For `x86_64-unknown-linux-gnu`</summary>
Notice the presence of `{c,}dylib` and `proc-macro`:
```
bin
cdylib
dylib
lib
proc-macro
rlib
staticlib
```

### Documentation
I added an entry in the unstable book's print request section to document this `supported-crate-types` print request.
### Unresolved questions
- [ ] (Name bikeshedding) is `supported-crate-types` a good name for the print request? I'm inclined to say it's good enough for an unstable print request, but may be worth revisiting at stabilization time.
### Stability
This print request being added is *unstable* in this PR. A separate stabilization PR following the usual compiler flag stabilization procedure should be filed for stabilization after some baking time.
### Review remarks
Best reviewed commit-by-commit.

Update test for SGX now implementing `read_buf`
In #108326, `read_buf` was implemented for a variety of types, but SGX was saved for later. Update a test from then, now that #137355 implemented it for SGX types.

Add MIR pre-codegen tests to track #138544
I don't know how best to fix the problem yet, but wanted to check in some tests to demonstrate it and make sure that they get updated to keep it fixed if anyone does fix it 🙂
No code changes; just the tests for #138544.
rustdoc: Gate unstable `doc(cfg())` predicates
Fixes#138113
Since the extraction process treats `cfg(true)` as having no cfg attribute, we have to do the gating during parsing; so we remove the unused `features` arg from `Cfg::matches`
uefi: Add OwnedEvent abstraction
- Events are going to become quite important for Networking, so needed owned abstractions.
- Switch to OwnedEvent abstraction for Exit boot services event.

std: move process implementations to `sys`
As per #117276, this moves the implementations of `Process` and friends out of the `pal` module and into the `sys` module, removing quite a lot of error-prone `#[path]` imports in the process (hah, get it ;-)). I've also made the `zircon` module a dedicated submodule of `pal::unix`, hopefully we can move some other definitions there as well (they are currently quite a lot of duplications in `sys`). Also, the `ensure_no_nuls` function on Windows now lives in `sys::pal::windows` – it's not specific to processes and shared by the argument implementation.
- Document test intent to check for `-Whelp` suggestion if
`--print=lints` was specified.
- Move this test under `tests/ui/print-request/` and rename it to
`print-lints-help.rs` to better reflect what it is checking.
Slim `rustc_parse_format` dependencies down
`rustc_index` is only used for its size assertion macro, so demote it to a dev-dependency gated under testing instead. This allows the crate to built without having to wait for `syn` (pulled in by `rustc_index_macros`)
Alternatively we could inline the macro, though from the looks of it that will run into trouble with `rustc_randomized_layouts`
Provide optional `Read`/`Write` methods for stdio
Override more of the default methods for `io::Read` and `io::Write` for stdio types, when efficient to do so, and deduplicate unsupported types.
Tracked in https://github.com/rust-lang/rust/issues/136756.
try-job: x86_64-msvc-1
core: optimize `RepeatN`
...by adding an optimized implementation of `try_fold` and `fold` as well as replacing some unnecessary `mem::replace` calls with `MaybeUninit` helper methods.
Move some driver code around
`--emit mir`, `#[rustc_symbol_name]` and `#[rustc_def_path]` now run before codegen and thus work even if codegen fails. This can help with debugging.
rustdoc js: add nonnull helper and typecheck src-script.js
this removes ``@ts-nocheck`` from `src-script.js` and adds a `nonnull` helper function that assists in adding null checks to places where null values should be impossible.
r? `@notriddle`
Mark some std tests as requiring `panic = "unwind"`
This allows these test modules to pass on builds/targets without unwinding support, where `panic = "abort"` - the ignored tests are for functionality that's not supported on those targets.
rustdoc: Use own logic to print `#[repr(..)]` attributes in JSON output.
Switch away from `Debug`-like representation of `#[repr(..)]` attributes, and start using rustdoc's own logic for pretty-printing `#[repr(..)]` in rustdoc JSON.
Part of addressing #137645 but not a complete solution for it.
r? `@aDotInTheVoid`
hack: is_doc_subtype_of always returns true for TyAlias
it's worth noting that this function is only used in
the handling of "Methods from Deref", and we were previously
assuming all generic parameters were meaningless,
so this is still an improvment from the status quo.
this change means that we will have strictly less false positives
without adding any new false negitives.
