Because the three kinds of operand are now distinguished explicitly, we no longer need fiddly code to disambiguate counter IDs and expression IDs based on the total number of counters/expressions in a function. This does increase the size of operands from 4 bytes to 8 bytes, but that shouldn't be a big deal since they are mostly stored inside boxed structures, and the current coverage code is not particularly size-optimized anyway.
