0f0dc29264 Auto merge of #109971 - WaffleLapkin:yeet_ownership, r=Nilstrieb 
Yeet `owning_ref`

Based on the discussions from https://github.com/rust-lang/rust/pull/109948

This replaces `owning_ref` with a far simpler & safer abstraction.

d7056548f9 Yeet owning_ref 
Turns out
- `owning_ref` is unsound due to `Box` aliasing stuff
- `rustc` doesn't need 99% of the `owning_ref` API
- `rustc` can use a far simpler abstraction that is `OwnedSlice`

a2ee7592d6 Use &IndexSlice instead of &IndexVec where possible 
All the same reasons as for `[T]`: more general, less pointer chasing, and `&mut IndexSlice` emphasizes that it doesn't change *length*.

eeb5b782a6 Improve the rustc_data_structures::sync module doc comment. 
Also, `MTRef<'a, T>` is a typedef for a reference to a `T`, but in
practice it's only used (and useful) in combination with `MTLock`, i.e.
`MTRef<'a, MTLock<T>>`. So this commit changes it to be a typedef for a
reference to an `MTLock<T>`, and renames it as `MTLockRef`. I think this
clarifies things, because I found `MTRef` quite puzzling at first.

Rollup merge of #107718 - Zoxc:z-time, r=nnethercote 
Add `-Z time-passes-format` to allow specifying a JSON output for `-Z time-passes`

This adds back the `-Z time` option as that is useful for [my rustc benchmark tool](https://github.com/Zoxc/rcb), reverting https://github.com/rust-lang/rust/pull/102725. It now uses nanoseconds and bytes as the units so it is renamed to `time-precise`.

Rename `MapInPlace` as `FlatMapInPlace`.

After removing the `map_in_place` method, which isn't much use because modifying every element in a collection such as a `Vec` can be done trivially with iteration.

9b60e6c68f Auto merge of #108312 - michaelwoerister:hash-set-not-hash-stable, r=eholk 
Do not implement HashStable for HashSet (MCP 533)

This PR removes all occurrences of `HashSet` in query results, replacing it either with `FxIndexSet` or with `UnordSet`, and then removes the `HashStable` implementation of `HashSet`. This is part of implementing [MCP 533](https://github.com/rust-lang/compiler-team/issues/533), that is, removing the `HashStable` implementations of all collection types with unstable iteration order.

The changes are mostly mechanical. The only place where additional sorting is happening is in Miri's override implementation of the `exported_symbols` query.
