Rollup merge of #119145 - aDotInTheVoid:variantdata-struct-struct, r=compiler-errors

2023-12-20T20:18:59+00:00

Give `VariantData::Struct` named fields, to clairfy `recovered`. Implements https://github.com/rust-lang/rust/pull/119121#discussion_r1431467066. Supersedes #119121 This way, it's clear what the bool fields means, instead of having to find where it's generated. Changes both ast and hir. r? `@compiler-errors`

Add check for possible CStr literals in pre-2021 Fixes [#118654](https://github.com/rust-lang/rust/issues/118654) Adds information to errors caused by possible CStr literals in pre-2021. The lexer separates `c"str"` into two tokens if the edition is less than 2021, which later causes an error when parsing. This error now has a more helpful message that directs them to information about editions. However, the user might also have written `c "str"` in a later edition, so to not confuse people who _are_ using a recent edition, I also added a note about whitespace. We could probably figure out exactly which scenario has been encountered by examining spans and editions, but I figured it would be better not to overcomplicate the creation of the error too much. This is my first code PR and I tried to follow existing conventions as much as possible, but I probably missed something, so let me know!

Give `VariantData::Struct` named fields, to clairfy `recovered`.
