feature request: #[feature] awareness in MSRV-gated lints #14477

@tamird

Description

@tamird

Some lints, such as borrow_as_ptr have conditional behavior based on MSRV:

let (suggestion, span) = if msrv.meets(cx, msrvs::RAW_REF_OP) {

In Rust-for-Linux, this is not sufficient because we enable a number of unstable features when we are reasonably confident their behavior won't change before stabilization, or because we know they have been stabilized without API change in a version that exceeds our configured MSRV.

It would be extremely helpful if these MSRV checks could be taught to also respect #[feature] attributes that enable unstable features ahead of the MSRV having been met. This is especially tricky when API has actually changed between the configured MSRV and the feature's actual stabilization.
