When I wrote the test I assumed we'd guarantee ABI compatibility to be "structural" wrt repr(C) types, i.e. if two repr(C) types have all their fields be pairwise ABI-compatible then the types are ABI-compatible. That got removed from the ABI compatibility docs before they landed, though, so let's also remove it from this test.

interpret: remove outdated FIXME

The rule about `repr(C)` types with compatible fields got removed from the ABI compat docs before they landed, so this FIXME here is no longer correct. (So this is basically a follow-up to rust-lang#130185, doing some more cleanup around deciding not to guarantee ABI compatibility for structurally compatible `repr(C)` types.)
