I have squashed the commits down more sensibly. Once CI passes this is good to go. |

Failures are simply Travis Mac horribleness and #23796. |

In #23628, we deprecated omitting indices over dimensions that are not of length 1. Unfortunately the 0-index case got left behind. This brings it into consistency. In short, once this deprecation is removed, `A[]` will _also_ assert that there is only one element in `A`.

This is the final step that finally closes #14770 and completes the circle on trailing indices and singleton dimensions. After this deprecation goes through, the final state of affairs will be:
1. (This is the status quo before, too.)1. (This is the part that's becoming more restrictive.)I haven't run the full test-suite yet, so I imagine there may be a few deprecations there that I've missed. And I still need to add NEWS. ButThis is, by and large, a very benign change. Very few places seem to be relying on this behavior.
