Not only this is not a part of the vector extension version 1.0, 8-bit vector AMO instructions will conflict to byte-granularity AMO instructions of the Zabha extension (containing subword AMO instructions) in the fast track.

The current vector spec (draft) also states that vector AMO encodings are likely to change, making keeping vector AMO as-is less usable.

This commit removes all vector AMO instructions but not VI_AMO macro.

Funny. I'll close this one since I've merged its twin.
