Thanks for clarifying the spec and fixing assumptions. It looks like there is a temptation to assume that access to a frame index must have non-empty memoperands. But that would be totally unenforceable. If there's a performance issue, it's probably better to fix cases where LLVM drops memoperands rather than make those assumptions.
