Yes, very likely, though it would require a "Great Renaming." It's probably
better that we do this sooner rather than later, as we're likely to be adding
opcodes.

The general idea would be that the wasm opcodes are the canonical names, and we
would change internal opcodes and machine ops to match. I'll take an action-item
to do this soon.
