701 This function is basically just a big switch statement. Earlier versions
702 used tables to look up the function to use, but
703 - if the table contains both assembler and disassembler functions then
704 the disassembler contains much of the assembler and vice-versa,
705 - there's a lot of inlining possibilities as things grow,
706 - using a switch statement avoids the function call overhead.
708 This function could be moved into `parse_insn_normal', but keeping it
