These tend to have special handling in a bunch of places anyway, so the variant helps remember that. And I think it's easier to grok than non-Scalar Aggregates sometimes being `Immediates` (like I got wrong and caused 109992). As a minor bonus, it means we don't need to generate poison LLVM values for them to pass around in `OperandValue::Immediate`s.

…ompiler-errors Add a distinct `OperandValue::ZeroSized` variant for ZSTs These tend to have special handling in a bunch of places anyway, so the variant helps remember that. And I think it's easier to grok than `Aggregate`s sometimes being `Immediates` (after all, I previously got that wrong and caused rust-lang#109992). As a minor bonus, it means we don't need to generate poison LLVM values for ZSTs to pass around in `OperandValue::Immediate`s. Inspired by rust-lang#110021 (comment), so r? ``@compiler-errors``
…cked, r=WaffleLapkin Uplift `clippy::invalid_utf8_in_unchecked` lint This PR aims at uplifting the `clippy::invalid_utf8_in_unchecked` lint into two lints. ## `invalid_from_utf8_unchecked` (deny-by-default) The `invalid_from_utf8_unchecked` lint checks for calls to `std::str::from_utf8_unchecked` and `std::str::from_utf8_unchecked_mut` with an invalid UTF-8 literal. ### Example ```rust unsafe { std::str::from_utf8_unchecked(b"cl\x82ippy"); } ``` ### Explanation Creating such a `str` would result in undefined behavior as per documentation for `std::str::from_utf8_unchecked` and `std::str::from_utf8_unchecked_mut`. ## `invalid_from_utf8` (warn-by-default) The `invalid_from_utf8` lint checks for calls to `std::str::from_utf8` and `std::str::from_utf8_mut` with an invalid UTF-8 literal. ### Example ```rust std::str::from_utf8(b"ru\x82st"); ``` ### Explanation Trying to create such a `str` would always return an error as per documentation for `std::str::from_utf8` and `std::str::from_utf8_mut`. ----- Mostly followed the instructions for uplifting a clippy lint described here: rust-lang#99696 (review) ``@rustbot`` label: +I-lang-nominated r? compiler ----- For Clippy: changelog: Moves: Uplifted `clippy::invalid_utf8_in_unchecked` into rustc
