The idea of this pass is to promote small bit-sizes to larger, supported bit-sizes for certain operations. It doesn't handle emulating large bit-size operations on smaller bit-sizes; passes like nir_lower_int64 and nir_lower_doubles handle that. So, assert that we aren't shrinking the bit-size, as this will almost certainly produce incorrect results.
