Warner Losh 973bfe6c4a 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)
