Sure. I didn't have the bandwidth this week due to a non SPIRV ticket.

I've tried the implicit uses but it won't work because some of the generic opcodes won't accept extra operands through implicit uses (the machine verifier rejects the IR).

@s-perron If you can help with this I'd really appreciate it. I'm not familiar enough with the whole backend.
