Auto merge of #77566 - Marwes:smaller_hashmap, r=Amanieu
feat: Update hashbrown to instantiate less llvm IR

Includes https://github.com/rust-lang/hashbrown/pull/204 and https://github.com/rust-lang/hashbrown/pull/205 (not yet merged) which both serve to reduce the amount of IR generated for hashmaps.

Inspired by the llvm-lines data gathered in https://github.com/rust-lang/rust/pull/76680 (cc `@Julian-Wollersberger)`
