Lots of changes due to formatting of the markdown table, but if you choose to "view in rich diff" you should see the changes more clearly.

v8 implementation orders narrow before widen, figured we can do that
here too.

These had previous consensus, where we agreed they are useful to include, merging.

Can these opcodes be renumbered to leave space for i64 variants of these instructions?

I was advised to put these opcodes at the end, I don't think these are finalized or anything yet, so it should be okay to renumber them.
