Interesting idea. Some initial thoughts:
- The HINT instructions are not included in the constant time guarantee, and this approach doesn't account for that
- A different name is probably need, as these instructions are only known to be constant time if zkt is enabled, and we'll need something similar for zvkt.
I'll put this on the agenda for the RISC-V LLVM sync-up call tomorrow.
