vc4: Drop some confused code about pack/unpack handling.
At one point I thought packs and unpacks were in the same field of the
instruction. They aren't. These instructions therefore never cause a
pack.
total instructions in shared programs: 89472 -> 89390 (-0.09%)
instructions in affected programs: 15261 -> 15179 (-0.54%)
