pointer_structural_match lint will become a hard error soon

[RalfJung]

This crate triggers the pointer_structural_match lint:

cambridge-asm/lib/src/inst.rs

Line 286 in 587d227

f => Ok(Self::Parent($parent::from_func_ptr(f)?)),

Matching against function pointers is not reliable and will become a hard error once rust-lang/rust#124661 lands, as was decided in rust-lang/rfcs#3535. I recommend comparing with == instead (though that will be just as unreliable).
