Kevin Lawton 4e51dcae40 Converted all the remaining available separate fields in bxInstruction_c 
to bitfields.  bxInstruction_c is now 24 bytes, including 4 for
the memory addr resolution function pointer, and 4 for the
execution function pointer (16 + 4 + 4).

Coded more accessors, to abstract access from most code.
