This change also adds a few utility functions as well and extend most mir and ty ADTs to implement PartialEq and Eq.

Fixes rust-lang/project-stable-mir#32

Equality for things containing Span has bitten us a few times in rustc. Things like mir::Constant comparing as inequal if they have different spans is surprising, but you also don't want them to compare as equal. What do you need it for?

Equality for things containing Span has bitten us a few times in rustc. Things like mir::Constant comparing as inequal if they have different spans is surprising, but you also don't want them to compare as equal. What do you need it for?

My initial use case was testing. In the long run, I think it is very helpful to store many of these constructs in hash maps, even though I haven't derived Hash yet.

For cases like Constant, we could eventually create a different trait or a method that only compare semantics, not structure.

We could also add comparison for fewer constructs for now, although removing some of them might make all the other ones hard to implement.
