The wasm-scope-info-liftoff.js and wasm-set-breakpoint-liftoff.js tests
were originally testing the Liftoff path (when we still had the Wasm
interpreter), and have received some updates along the way. Nowadays the
interpreter is going and the non-liftoff versions of these tests don't
provide any additional test coverage, but are merely a slightly less
updated version of the liftoff test.
