description:
Storing four-byte pointers to two-character strings is silly.  All the
auxilliary tables used by the disassembler are now char[][].

The main table still uses pointers because:
 - the longest instruction name, "imbrange" is >7 characters long, which would
   make the field length wasteful.
 - GCC spots that most of the formats are shared and makes them pointers to the
   same string, so turning them into char[8] would be counter-productive.
