identity_op in some scenarios

[pacak]

Summary

I find myself disabling identity_op lint over and over again.

When complaining about identity ops clippy should look around. If there's a similar construct in nearby context but the op is not an identity - clippy should keep quiet.

Lint Name

clippy::identity_op

Reproducer

I tried this code:

             let mut v = 0;
              v |= (value.normal_market as u16) << 0;
              v |= (value.oddlot_market as u16) << 1;
              v |= (value.spot_market as u16) << 2;
              v |= (value.auction_market as u16) << 3;

I saw this happen:

consider reducing it to: `(value.normal_market as u16)`

I expected to see this happen:

Code is accepted as is - the op is identity, but it is there to maintain code uniformity

#3430 - similar case was resolved by allowing it with constants: #5602 but in my case those are bools and other bit packing constructions.
