Comment:
I think the register allocator is confused because `x` is used without
being assigned to, so the allocator doesn't think it's live. If you add
an assignment to `x` it compiles without error.
Furthermore, the new graph-colouring allocator handles this just fine, so
I'm going to close the bug.
