626b2987a9 Introduce UnionIntoIdxSet and SubtractFromIdxSet traits. 
They let `union()`, `union_sparse()` and `union_hybrid()` be merged.
Likewise for subtract()`, `subtract_sparse()` and `subtract_hybrid()`.

180052d5f7 Rename universe_size as domain_size. 
Because `domain` is a more obvious term than `universe` for this
concept.

Rollup merge of #53562 - varkor:bastion-of-the-turbofish, r=nagisa 
Lament the invincibility of the Turbofish

Here a test case is added to ensure that any others attempting to drive the Turbofish to extinction have second thoughts. Previously the [entire test suite would succeed](https://github.com/rust-lang/rust/pull/53511) if generic arguments were accepted without disambiguation, making for [confusing and heartbreaking circumstances](https://github.com/rust-lang/rfcs/pull/2527).

Rollup merge of #53503 - kornelski:master, r=dtolnay 
Discourage overuse of mem::forget

Some uses of `mem::forget` have been replaced by better methods of `Box`, so I've removed obsoleted use-cases from these docs.

I've removed emphasis on leaking, because it's not obvious `mem::forget` does not guarantee leaking of memory: memory of stack-allocated objects and values partially moved out of `Box` will still be freed. That's a potential error when used to pass objects to FFI, so it's better to direct users to `Box::into_raw` instead.

002f03b654 Make SparseBitMatrix a bit lazier. 
Currently when a row is instantiated in SparseBitMatrix, any missing
rows prior to it are also fully instantiated.

This patch changes things so that those prior rows are minimally
instantiated (with a `None`). This avoids a decent number of allocations
in NLL, speeding up several benchmarks by up to 0.5%.

The patch also removes two unused methods, `len()` and
`iter_enumerated()`.

827e57c2f6 Auto merge of #53459 - petrochenkov:stabmore, r=nrc 
Stabilize a few secondary macro features

- `tool_attributes` - closes https://github.com/rust-lang/rust/issues/44690
- `proc_macro_path_invoc` - this feature was created due to issues with tool attributes (https://github.com/rust-lang/rust/issues/51277), those issues are now fixed (https://github.com/rust-lang/rust/pull/52841)
- partially `proc_macro_gen` - this feature was created due to issue https://github.com/rust-lang/rust/issues/50504, the issue is now fixed (https://github.com/rust-lang/rust/pull/51952), so proc macros can generate modules. They still can't generate `macro_rules` items though due to unclear hygiene interactions.
