It's because this will become a frequent pattern in future work, where we have to follow the same pattern of 1) convert float type -> int type, 2) invoke getRuntimeVF, 3) convert result back to FP. I wrote this patch on the basis that we'd prefer to reduce code duplication scattered throughout the vectoriser. It will make future patches in the area of tail-folding smaller.
