895 This function is basically just a big switch statement. Earlier versions
896 used tables to look up the function to use, but
897 - if the table contains both assembler and disassembler functions then
898 the disassembler contains much of the assembler and vice-versa,
899 - there's a lot of inlining possibilities as things grow,
