I think it's fine to land these, but it'd be good to add a FIXME to reenable them once we add `__main` emulation to ORC?

The ORC runtime isn't relevant here, but the RuntimeDyld / JITLink distinction is: These are `llvm-jitlink` tests for the new JIT linker. The pure assembly cases are hand written, so have no reference to `__main`, but the new `.ll` ones are compiled by `llc` which will add a reference -- that's probably what's caused the difference.
