/*!
* On x86_64-linux-gnu and possibly other platforms, structs get 8-byte "preferred" alignment,
* but their "ABI" alignment (i.e., what actually matters for data layout) is the largest alignment
* of any field. (Also, `u64` has 8-byte ABI alignment; this is not always true).
*
* On such platforms, if monomorphize uses the "preferred" alignment, then it will unify
* `A` and `B`, even though `S<A>` and `S<B>` have the field `t` at different offsets,
* and apply the wrong instance of the method `unwrap`.
