Generally we would not bother with `inreg` except for instruction operands that have to go in SGPRs. But it doesn't really matter. At worst, it will bloat the output with some extra SGPR-to-VGPR copies.

Again it doesn't really matter. Personally I would use vector arguments because it keeps the IR nice and short.
