Rationale:
- `abort()` lowers to `wasm32::unreachable()` anyway.
- `abort()` isn't `unsafe`.
- `abort()` matches the comment better.
- `abort()` avoids confusion by future readers (e.g.
rust-lang#81527): the naming of wasm's
`unreachable' instruction is a bit unfortunate because it is not
related to the `unreachable()` intrinsic (intended to trigger UB).
Codegen is likely to be different since `unreachable()` is `inline`
while `abort()` is `cold`. Since it doesn't look like we are expecting
here to trigger this case, the latter seems better anyway.
