724 This function is basically just a big switch statement. Earlier versions
725 used tables to look up the function to use, but
726 - if the table contains both assembler and disassembler functions then
727 the disassembler contains much of the assembler and vice-versa,
728 - there's a lot of inlining possibilities as things grow,
729 - using a switch statement avoids the function call overhead.
730
731 This function could be moved into `print_insn_normal', but keeping it
732 separate makes clear the interface between `print_insn_normal' and each of
733 the handlers. */
