Add profiler to bootstrap command
This PR adds command profiling to the bootstrap command. It tracks the total execution time and records cache hits for each command. It also provides the ability to export execution result to a JSON file. Integrating this with Chrome tracing could further enhance observability.

triagebot.toml: ping lolbinarycat if tidy extra checks were modified
I rewrote a large chunk of this module, and plan to do further changes to it (namely moving rustdoc_js checks into it), so it would be nice to keep up with and provide feedback on any changes to it, at least for the immediate future.

Assorted `run-make-support` maintenance
This PR should contain no functional changes.
- Commit 1: Removes the support library's CHANGELOG. In the very beginning, I thought maybe we would try to version this library. But this is a purely internal test support library, and it's just extra busywork trying to maintain changelog/versions. It's also hopelessly outdated.
- Commit 2: Resets version number to `0.0.0`. Ditto on busywork.
- Commit 3: Bump `run-make-support` to Edition 2024. The support library was already "compliant" with Edition 2024.
- Commit 4: Slightly organizes the support library dependencies.
- Commit 5: Previously, I tried hopelessly to maintain some manual formatting, but that was annoying because it required skipping rustfmt (so export ordering etc. could not be extra formatted). Give up, and do some rearrangements / module prefix tricks to get the `lib.rs` looking at least *reasonable*. IMO this is not a strict improvement, but I rather regain the ability to auto-format it with rustfmt.
- Commit {6,7}: Noticed in rust-lang/rust#143669 that we apparently had *both* {`is_msvc`, `is_windows_msvc`}. This PR removes `is_msvc` in favor of `is_windows_msvc` to make it unambiguous (and only retain one way of gating) as there are some UEFI targets which are MSVC but not Windows.

Re-expose nested bodies in rustc_borrowck::consumers
After https://github.com/rust-lang/rust/pull/138499, it's not possible anymore to get borrowck information for nested bodies via `get_body_with_borrowck_facts`. This PR re-exposes nested bodies by returning a map containing the typeck root and all its nested bodies. To collect the bodies, a map is added to `BorrowCheckRootCtxt`, and a body is inserted every time `do_mir_borrowck` is called.

Resolver: refact macro map into external and local maps
Puts `MacroData` inside of the `ResolverArena` and splits `macro_map` into 2 maps: `local_macro_map` and `external_macro_map`. This way `get_macro_by_def_id` can take a `&Resolver` instead of a mutable one.

docs: document trait upcasting rules in `Unsize` trait
The trait upcasting feature stabilized in 1.86 added new `Unsize` implementation, but this wasn't reflected in the trait's documentation.
And leave only the type stuff without it.
This is because most expression stores don't have anything but types (e.g. generics, fields, signatures) so this saves a lot of memory.
This saves 58mb on `analysis-stats .`.
Instantiate auto trait/`Copy`/`Clone`/`Sized` before computing constituent types binder
This makes the binder logic w.r.t. coroutines a bit simpler.
r? lcnr
We need it because `global_asm!()` is an item. It's unfortunate that such thing can slip in and I see no way to automatically catch that, but thankfully analysis-stats on self has caught that.
Let `rvalue_creates_operand` return true for *all* `Rvalue::Aggregate`s
~~Draft for now because it's built on Ralf's rust-lang/rust#143291~~
Inspired by https://github.com/rust-lang/rust/pull/138759#discussion_r2156375342 where I noticed that we were nearly at this point, plus the comments I was writing in rust-lang/rust#143410 that reminded me a type-dependent `true` is fine.
This PR splits the `OperandRef::builder` logic out to a separate type, with the updates needed to handle SIMD as well. In doing so, that makes the existing `Aggregate` path in `codegen_rvalue_operand` capable of handing SIMD values just fine.
As a result, we no longer need to do layout calculations for aggregate result types when running the analysis to determine which things can be SSA in codegen.
`rustc_pattern_analysis`: always check that deref patterns don't match on the same place as normal constructors
In rust-lang/rust#140106, deref pattern validation was tied to the `deref_patterns` feature to temporarily avoid affecting perf. However:
- As of rust-lang/rust#143414, box patterns are represented as deref patterns in `rustc_pattern_analysis`. Since they can be used by enabling `box_patterns` instead of `deref_patterns`, it was possible for them to skip validation, resulting in an ICE. This fixes that and adds a regression test.
- External tooling (e.g. rust-analyzer) will also need to validate matches containing deref patterns, which was not possible. This fixes that by making `compute_match_usefulness` validate deref patterns by default.
In order to avoid doing an extra pass for anything with patterns, the second commit makes `RustcPatCtxt` keep track of whether it encounters a deref pattern, so that it only does the check if so. This is purely for performance. If the perf impact of the first commit is negligible and the complexity cost introduced by the second commit is significant, it may be worth dropping the latter.

Apply effects to `otherwise` edge in dataflow analysis
This allows `ElaborateDrops` to remove drops when a `match` wildcard arm covers multiple no-Drop enum variants. It modifies dataflow analysis to update the `MaybeUninitializedPlaces` and `MaybeInitializedPlaces` data for a block reached through an `otherwise` edge.
Fixesrust-lang/rust#142705.
