We might consider to move to this interface and do some actual computation on the parametric loop trip counts instead of limiting ourselfs to integer loop trip counts... often the LLVM vectorizer does not vectorize loops even if they are annotated parallel and have a few simple load-binop-store chains (e.g., bicg when it's parallelized in the outer most dimension and therefore doesn't have a reduction in the innermost loop any more [due to privatization to be exact]).
