Make some trivial functions `#[inline(always)]`

This is some kind of follow-up of PRs like rust-lang/rust#85218, rust-lang/rust#84061, rust-lang/rust#87150. Functions that do very basic operations are made `#[inline(always)]` to avoid pessimizing them in debug builds when compared to using built-in operations directly.
