Rollup merge of #82514 - flip1995:clippyup, r=Manishearth

Update Clippy

Bi-weekly Clippy update.

This updates `Cargo.lock`, so probably needs rollup=never. (0046d7c)

a6dd9b9 fixes things in Clippy, so that it can be build and tested. This needs proper fixing in Clippy, but I didn't want this to block the sync.

r? `@Manishearth`
