 898    This function is basically just a big switch statement.  Earlier versions

 900    - if the table contains both assembler and disassembler functions then
 901      the disassembler contains much of the assembler and vice-versa,
 902    - there's a lot of inlining possibilities as things grow,
 903    - using a switch statement avoids the function call overhead.
 904
