This corresponds with the previous work to make shape.broadcast nary.
Additionally, simplify the ConvertShapeConstraints pass. It now doesn't
lower an implicit shape.is_broadcastable. This is still the same in
combination with shape-to-standard when the 2 passes are used in either
order.

Because cstr operations allow more instruction reordering than asserts, we only
lower cstr_broadcastable to std ops with cstr_require. This ensures that the
more drastic lowering to asserts can happen specifically with the user's desire.
