Fix varying packing of I/O block fields The sorting algorithm didn't keep the fields in order, which made them receive arbitrary locations. The SPIR-V transformer assigns the location on the whole block instead of individual members, which was incorrect in this situation. The SPIR-V transformer could have been modified to decorate each field of the I/O block with a location. This change instead sorts the fields in such a way that I/O block fields are allocated contiguously, which allows the SPIR-V transformer to function unchanged.
