Better codegen for record's Equals member

[DoctorKrolic]

Closes #70221

One of comments in the issue also mentions GetHashCode. I tried it locally (by "it" I mean calling GetHashCode directly when overriden in structs) and it turns out that it takes a bit more IL due to ceremony with constrained call, so I didn't include those changes

Putting a hold on the PR until the underlying issue gets LDM sign off.

@jaredpar Do you have this question scheduled for an LDM? Correct me if I am wrong, but this is a weekly event, isn't it? I don't think it would take much discussion time to make a decision here

Correct me if I am wrong, but this is a weekly event, isn't it?

Usually but not always.

Do you have this question scheduled for an LDM?

No. Don't believe anyone has put this on the agenda.

@RikkiGibson, @CyrusNajmabadi in case they have time to bring this in the next few weeks.

[CyrusNajmabadi]

I'll look into it. I don't find it hugely important. But if we have time, then sure:-)

[DoctorKrolic]

@CyrusNajmabadi for a friendly reminder

[CyrusNajmabadi]

Thanks for the reminder. Will try to bring to LDM soon.

@CyrusNajmabadi @DoctorKrolic this PR by itself is not enough to bring to LDM. There needs to be an actual proposal checked into csharplang.

[DoctorKrolic]

You mean something like this?
