 557    This function is basically just a big switch statement.  Earlier versions
 558    used tables to look up the function to use, but
 559    - if the table contains both assembler and disassembler functions then
 560      the disassembler contains much of the assembler and vice-versa,
 561    - there's a lot of inlining possibilities as things grow,
 562    - using a switch statement avoids the function call overhead.
 563
 564    This function could be moved into `parse_insn_normal', but keeping it
 565    separate makes clear the interface between `parse_insn_normal' and each of
 566    the handlers.  It's also needed by GAS to insert operands that couldn't be
