   Cache-line constants were tried with the StarkCPU and seemed to work   
   fine, but wasted cache-line space when constants and instructions could   
   not be packed evenly into the cache-line.   
      
   However, for Qupls2026 using constants stored on the cache-line might be   
   just as efficient storage wise as having the constants follow   
   instruction words because of the 48-bit word width. Constants typically   
   do not need to be multiples of 48 bits. If stored on the cache-line they   
   could be multiples of 16-bits. There are potentially 32-bits of wasted   
   space if an instruction is not able to be packed onto the cache-line.   
   There may just be as much wasted space due to the support of over-sized   
   constants in-line with 48-bit parcels. A 32-bit constant uses 48 bits,   
   wasting 16-bits of storage.
