3d7677d91a Rollup merge of #106970 - kylematsuda:earlybinder-item-bounds, r=lcnr 
Switch to `EarlyBinder` for `item_bounds` query

Part of the work to finish #105779 (also see https://github.com/rust-lang/types-team/issues/78).

Several queries `X` have a `bound_X` variant that wraps the output in `EarlyBinder`. This adds `EarlyBinder` to the return type of the `item_bounds` query and removes `bound_item_bounds`.

Remove double spaces after dots in comments

Most of the comments do not have double spaces, so I assume these are typos.

d1449560e3 Auto merge of #105094 - Swatinem:generator-not-future, r=compiler-errors 
Make sure async constructs do not `impl Generator`

Async lowering turns async functions and blocks into generators internally.
Though these special kinds of generators should not `impl Generator` themselves.
The other way around, normal generators should not `impl Future`.

This was discovered in https://github.com/rust-lang/rust/pull/105082#issuecomment-1332210907 and is a regression from https://github.com/rust-lang/rust/pull/104321.

Move failing test to ui

Changes this test from incremental to ui, and mark it as failing and a known bug.
Does not cause the compiler to ICE, so should be ok.
