These changes make sense to me. For example, there is no `vector.maskedstore` on tensors, so the corresponding folder (`vector.scatter` -> `vector.maskedstore`) has to be disabled. This boils down to asymmetry between `vector.scatter`/`vector.gather` and `vector.maskedstore`/`vector.maskedload` (the former take tensros + memref, the latter only takes memrefs). 

LGTM % minor nits, thanks!
