Contrary to my comments in other PRs in the stack, I think it is fine to put these instructions in a separate file, as it is a new "class" of instructions (cryptography). I wouldn't bind them to a specific extension name though, something like `SparcInstrInfoCrypto.td` maybe?

Not a strong objection (in other PRs too), it is a personal PoV.
