is_aligned method for pointers

[Lokathor]

Just a quick request for an is_aligned method to be on pointers so that we can have an official way to check alignment.

This was talked about a bunch in rust-lang/rfcs#2043

If you're ok with false-negatives, you can just use .align_offset() == 0.

[Lokathor]

But you actually need to pass in an alignment, so you also need to make sure that the alignment you pass is correct for the type that the pointer currently is. And even after that difficulty you don't get an assured answer. That seems a lot less good.

I think this is taken care of by #96284

Closing because of #96284
