754 used tables to look up the function to use, but
755 - if the table contains both assembler and disassembler functions then
756 the disassembler contains much of the assembler and vice-versa,
757 - there's a lot of inlining possibilities as things grow,
758 - using a switch statement avoids the function call overhead.
