Explicitly separating the parameters here allows us to use the correct ACLE types for all variables and operations, enabling the use of the compiler flag -flax-vector-conversions=none (which is the primary purpose of this patch series). It is for code sanitisation, rather than optimisation.

We have a large set of patches providing significant uplift for interpolation functions that will be pushed after this series.
