[o1vm] Ensure the instruction passed into the interpreter is the one pointed to by the IP

[Fizzixnerd]

Or otherwise refactor it so no instruction is passed in, and we just use the opcode from the IP.

This is in, for instance, https://github.com/o1-labs/proof-systems/blob/master/o1vm/src/mips/interpreter.rs#L987 the interpret functions for the instructions.

Is this still open?
If so, I would like to take this up.
Some more context would be helpful

Hi there!

I'm currently working on this issue, sorry! This issue is part of the as-yet-unfinished o1vm work that we are doing, so I think it would be difficult to give more context until we've actually released the feature it's a part of. Sorry, I meant for the tag to be for people working on the VM already, I didn't mean to confuse!

No issues
Will look for other issues to get started
