Not sure I'm allowed to paste the code in for them, but that's what's going on
here: with -mtune=thead-c906 both cases have a single store, the default is for
Rocket which has very slow misaligned accesses.
That said, I think we actually have a bug here: if the extern symbol was really
of unknown alignment then sharing the lui might not work.
