  MFp4: overhaul of resource allocation
  
  Rather than have a twisty maze of special case allocations, move
  instead to a data driven allocation.  This should be the most robust
  way to cope with the resource problems that the multiplicity of ways
  of encoding 5 registers that have the misfortune of not being a power
  of 2 nor contiguous.
  
  Also, make it less impossible that pccard will work.  I've not been able
  to get my libretto floppy working, but it now fails later than before.
  
  phk and I had similar ideas on this during the 5.3 release cycle, but
  it wasn't until recently that I could test more than one allocation
  scenario.
  
  MFC After: 1 month (5.4 if possible, 5.5 if not)
