Exposing STARTUPINFOW.wShowWindow in CommandExt trait
Hi:
I needed a way to control how a new process's window is displayed in Windows (normal, minimized, maximized, etc).
I noticed that there is no direct way to do that (I even searched for crates doing this, but didn't find any).
Inspecting the standard library source code, I figured that it would be a good addition to CommandExt trait that allows some Windows specific customization to a Command.
This is my first time contributing to Rust, so please bear with me if I'm not following the rules :)
Migrate `extern-flag-pathless`, `silly-file-names`, `metadata-dep-info`, `cdylib-fewer-symbols` and `symbols-include-type-name` `run-make` tests to rmake
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
`cdylib-fewer-symbols` demands a Windows try-job. (Almost guaranteed to fail, but 7 years is a long time)

`#[doc(alias)]`'s doc: say that ASCII spaces are allowed
PR #77570 allowed ASCII spaces in doc aliases, but the documentation wasn't updated to say so.

Fixup failing fuchsia tests
The Fuchsia platform passes all tests with these changes. Two tests are ignored because they rely on Fuchsia not returning a status code upon a process aborting. See #102032 and #58590 for more details on that topic.
Many formatting changes are also included in this PR.

Update `f16`/`f128` FIXMEs that needed `(NEG_)INFINITY`
Just a small fix to the pattern matching tests now that we can. Also contains a small unrelated comment tweak.
More trait error reworking
More work on #127492, specifically those sub-bullets under "Move trait error reporting to `error_reporting::traits`". Stacked on top of #127493.
This does introduce new `TypeErrCtxt.*Ext` traits, but those will be deleted soon. Splitting this work into bite-sized pieces is the only way that it's gonna be feasible to both author and review ❤️

Automatically taint when reporting errors from ItemCtxt
This isn't very robust yet, as you need to use `itemctxt.dcx()` instead of `tcx.dcx()` for it to take effect, but it's at least more convenient than sprinkling `set_tainted_by_errors` calls in individual places.

r? `@fmease`
Both test-panic-abort-nocapture.rs and test-panic-abort.rs assert the
stderr output of the test. On Fuchsia, if a test fails an assertion,
this output will contain a line noting the process returned the code
-1028 (ZX_TASK_RETCODE_EXCEPTION_KILL). But the asserted stderr output
lacks this note. Presumably this is because other platforms implement
-Cpanic=abort by killing the process instead of returned a status
code.
[Coverage][MCDC] Group mcdc tests and fix panic when generating mcdc code for inlined expressions.
### Changes
1. Group all mcdc tests to one directory.
2. Since mcdc instruments different mappings for boolean expressions with normal branch coverage as #125766 introduces, it would be better also trace branch coverage results in mcdc tests.
3. So far rustc does not call `CoverageInfoBuilderMethods::init_coverage` for inlined functions. As a result, it could panic if it tries to instrument mcdc statements for inlined functions due to uninitialized cond bitmaps. We can reproduce this issue by current nightly rustc and [the test](https://github.com/rust-lang/rust/pull/127234/files#diff-c81af6bf4869aa42f5c7334e3e86344475de362f673f54ce439ec75fcb5ac3e5) with flag `--release`. This patch fixes it.
This is adding a migration lint for the current (in the 2021 edition and previous)
to move expr to expr_2021 from expr

Fix regression in the MIR lowering of or-patterns
In https://github.com/rust-lang/rust/pull/126553 I made a silly indexing mistake and regressed the MIR lowering of or-patterns. This fixes it.
r? `@compiler-errors` because I'd like this to be merged quickly 🙏
Consolidate region error reporting in `rustc_infer`
More work on https://github.com/rust-lang/rust/issues/127492. Separate but important step, since I'm gonna likely pull everything else here into another module.
I don't think I'm confident whether `nice_region_error` should be a submodule of the new `rustc_infer::infer::error_reporting::region` module, so I left it alone for now.

Move trait selection error reporting to its own top-level module
This effectively moves `rustc_trait_selection::traits::error_reporting` to `rustc_trait_selection::error_reporting::traits`. There are only a couple of actual changes to the code, like moving the `pretty_impl_header` fn out of the specialization module for privacy reasons.
This is quite pointless on its own, but having `error_reporting` as a top-level module in `rustc_trait_selection` is very important to make sure we have a meaningful file structure for when we move **type** error reporting (and region error reporting, with which it's incredibly entangled currently) into `rustc_trait_selection`. I've opened a tracking issue here: #127492

Add Natvis visualiser and debuginfo tests for `f16`
To render `f16`s in debuggers on MSVC targets, this PR changes the compiler to output `f16`s as `struct f16 { bits: u16 }`, and includes a Natvis visualiser that manually converts the `f16`'s bits to a `float` which is can then be displayed by debuggers. `gdb`, `lldb` and `cdb` tests are also included for `f16` .
