Unrolled build for rust-lang#126057
Browse files Browse the repository at this point in the history
Rollup merge of rust-lang#126057 - Sunshine40:rustdoc-search-non-english, r=notriddle

Make html rendered by rustdoc allow searching non-English identifier / alias

Fix alias search result showing `undefined` description.

Inspired by rust-lang/mdBook#2393 .

Not sure if it's worth it adding full-text search functionality to rustdoc rendered html.
