Support mdBook preprocessors for TRPL in rustbook
`rust-lang/book` recently added two mdBook preprocessors. Enable `rustbook` to use those preprocessors for books where they are requested by the `book.toml` by adding the preprocessors as path dependencies, and ignoring them where they are not requested, i.e. by all the books other than TRPL at present.
Addresses rust-lang/book#3927
Don't build the `rust-demangler` binary for coverage tests
The coverage-run tests invoke `llvm-cov`, which requires us to specify a command-line demangler that it can use to demangle Rust symbol names.
Historically this used `src/tools/rust-demangler`, which means that we currently build two different command-line tools to help with the coverage tests (`rust-demangler` and `coverage-dump`).
However, it occurred to me that if we add a demangler mode to `coverage-dump` (which is only a handful of lines and no extra dependencies), then we only need to build one helper binary for the coverage tests, and there is no need for tests to build `rust-demangler` at all.
---
Note that the `rust-demangler` binary is separate from the `rustc-demangle` crate (which both `rust-demangler` and `coverage-dump` use as a dependency to do the actual demangling).
---
So the main benefits/motivations here are:
- Slightly faster builds after a fresh checkout or bootstrap bump.
- Making it clear that currently no tests actually need the `rust-demangler` binary, since the coverage tests can use their own tool instead.
coverage: Optionally instrument the RHS of lazy logical operators
(This is an updated version of #124644 and #124402. Fixes #124120.)
When `||` or `&&` is used outside of a branching context (such as the condition of an `if`), the rightmost value does not directly influence any branching decision, so branch coverage instrumentation does not treat it as its own true-or-false branch.
That is a correct and useful interpretation of “branch coverage”, but might be undesirable in some contexts, as described at #124120. This PR therefore adds a new coverage level `-Zcoverage-options=condition` that behaves like branch coverage, but also adds additional branch instrumentation to the right-hand-side of lazy boolean operators.
---
As discussed at https://github.com/rust-lang/rust/issues/124120#issuecomment-2092394586, this is mainly intended as an intermediate step towards fully-featured MC/DC instrumentation. It's likely that we'll eventually want to remove this coverage level (rather than stabilize it), either because it has been incorporated into MC/DC instrumentation, or because it's getting in the way of future MC/DC work. The main appeal of landing it now is so that work on tracking conditions can proceed concurrently with other MC/DC-related work.

Implement `needs_async_drop` in rustc and optimize async drop glue
This PR expands on #121801 and implements `Ty::needs_async_drop` which works almost exactly the same as `Ty::needs_drop`, which is needed for #123948.
Also made compiler's async drop code to look more like compiler's regular drop code, which enabled me to write an optimization where types which do not use `AsyncDrop` can simply forward async drop glue to `drop_in_place`. This made size of the async block from the [async_drop test](67980dd6fb/tests/ui/async-await/async-drop.rs) to decrease by 12%.
Rename HIR `TypeBinding` to `AssocItemConstraint` and related cleanup
Rename `hir::TypeBinding` and `ast::AssocConstraint` to `AssocItemConstraint` and update all items and locals using the old terminology.
Motivation: The terminology *type binding* is extremely outdated. "Type bindings" not only include constraints on associated *types* but also on associated *constants* (feature `associated_const_equality`) and on RPITITs of associated *functions* (feature `return_type_notation`). Hence the word *item* in the new name. Furthermore, the word *binding* commonly refers to a mapping from a binder/identifier to a "value" for some definition of "value". Its use in "type binding" made sense when equality constraints (e.g., `AssocTy = Ty`) were the only kind of associated item constraint. Nowadays however, we also have *associated type bounds* (e.g., `AssocTy: Bound`) for which the term *binding* doesn't make sense.
---
Old terminology (HIR, rustdoc):
```
`TypeBinding`: (associated) type binding
├── `Constraint`: associated type bound
└── `Equality`: (associated) equality constraint (?)
├── `Ty`: (associated) type binding
└── `Const`: associated const equality (constraint)
```
Old terminology (AST, abbrev.):
```
`AssocConstraint`
├── `Bound`
└── `Equality`
├── `Ty`
└── `Const`
```
New terminology (AST, HIR, rustdoc):
```
`AssocItemConstraint`: associated item constraint
├── `Bound`: associated type bound
└── `Equality`: associated item equality constraint OR associated item binding (for short)
├── `Ty`: associated type equality constraint OR associated type binding (for short)
└── `Const`: associated const equality constraint OR associated const binding (for short)
```

compiletest: clarify COMPILETEST_NEEDS_ALL_LLVM_COMPONENTS error
COMPILETEST_NEEDS_ALL_LLVM_COMPONENTS is a confusing name because elsewhere "needs" means "ignore when requirement not met", but here it means "fail when requirement not met".
remove tracing tree indent lines
This allows vscode to collapse nested spans without having to manually remove the indent lines. This is incredibly useful when logging the new solver. I don't mind making them optional depending on some environment flag if you prefer using indent lines

Fix "local crate" detection
`PackageId` is an opaque identifier whose internal format is subject to change, so looking up the names of local crates by ID is more robust than parsing the ID.
Resolves#3643.
compiletest: Unify `cmd2procres` with `run_command_to_procres`
Historical context: I originally added `run_command_to_procres` in #112300 and #114843, because I didn't like the overly-specific failure message in `cmd2procres`, but at the time I didn't feel confident enough to change the existing code, so I just added my own similar code.
Now I'm going back to remove this redundancy by eliminating `cmd2procress`, and adjusting all callers to use a slightly-tweaked `run_command_to_procres` instead.
drop_in_place: weaken the claim of equivalence with drop(ptr.read())
The two are *not* semantically equivalent in all cases, so let's not be so definite about this.
Fixes https://github.com/rust-lang/rust/issues/112015
Make `body_owned_by` return the `Body` instead of just the `BodyId`
fixes#125677
Almost all `body_owned_by` callers immediately called `body`, too, so just return `Body` directly.
This makes the inline-const query feeding more robust, as all calls to `body_owned_by` will now yield a body for inline consts, too.
I have not yet figured out a good way to make `tcx.hir().body()` return an inline-const body, but that can be done as a follow-up
Streamline `x fmt` and improve its output
- Removes the ability to pass paths to `x fmt`, because it's complicated and not useful, and adds `--all`.
- Improves `x fmt` output.
- Improves `x fmt`'s internal code.
