Functions in answer:

- `Ty::is_sized`
- `Ty::is_unpin`
- `Ty::is_copy_modulo_regions`

spastorino noticed some silly expressions like `item_id.def_id.def_id`.

This commit renames several `def_id: OwnerId` fields as `owner_id`, so
those expressions become `item_id.owner_id.def_id`.

`item_id.owner_id.local_def_id` would be even clearer, but the use of
`def_id` for values of type `LocalDefId` is *very* widespread, so I left
that alone.

compiletest: Refactor test rustcflags

Refactoring `host-rustcflags` and `target-rustcflags` from `Option<String>` to `Vec<String>`

Ref: rust-lang#102438

Prevent foreign Rust exceptions from being caught

Fix rust-lang#102715

Use the address of a static variable (which is guaranteed to be unique per copy of std) to tell apart if a Rust exception comes from local or foreign Rust code, and abort for the latter.

filter candidates in pick probe for diagnostics

Fixes rust-lang#103411, though also fine with closing this PR if my opinion (rust-lang#103411 (comment)) is shared that this doesn't need to  be fixed.

Rename some `OwnerId` fields.

`@spastorino` noticed some silly expressions like `item_id.def_id.def_id`.

This commit renames several `def_id: OwnerId` fields as `owner_id`, so those expressions become `item_id.owner_id.def_id`.

Accept `TyCtxt` instead of `TyCtxtAt` in `Ty::is_*` functions

Functions in answer:

- `Ty::is_freeze`
- `Ty::is_sized`
- `Ty::is_unpin`
- `Ty::is_copy_modulo_regions`

This allows to remove a lot of useless `.at(DUMMY_SP)`, making the code a bit nicer :3

Add missing impl blocks for item reexported from private mod in JSON output

Fixes rust-lang#102583.

Since we don't inline for the JSON output, the impl blocks from private modules are not present when we generate the output. To go around this limitation, in case the impl block doesn't have `#[doc(hidden)]` and is implementing a public item, we don't strip it.

fix typo in `try_reserve` method from `HashMap` and `HashSet`

Currently refers to the `reserve` method, instead of `try_reserve`. Other collections like [Vec](https://doc.rust-lang.org/std/vec/struct.Vec.html#method.try_reserve) & [VecDeque](https://doc.rust-lang.org/std/collections/vec_deque/struct.VecDeque.html#method.try_reserve) shows it well.
