After discussions on the child patch (D89031 <https://reviews.llvm.org/D89031>) we've decided to do things differently so instead of adapting vectorize.width to accept a tuple we're now adding a new vectorize.scalable.enable hint that can be used with vectorize.width to create a ElementCount. For the clang patch I also intend to update it so that we use a new vectorize_style #pragma instead of using vectorize_width to force scalable vectorisation.
