arc: Construct disassembler options dynamically
The idea of this change is simple: Populate a data structure, namely "disasm_option_and_arg_t" from "include/dis-asm.h", to encompass the disassembly options and their possible arguments. This will make it easier to manage or extend those options by adapting entries in a data structure, "arc_options". There will be lesser need to hard-code the options in the code itself. Moreover, ARC GDB will use this population function, "disassembler_options_arc ()", to enable the "set disassembler-option" for ARC targets. The gdb change will be in a separate patch though. The changes in this patch can be divided into: 1) Introduction of "disassembler_options_arc ()" that will return a "disasm_option_and_arg_t" structure representing the disassembly options and their likely arguments. 2) New data type "arc_options_arg_t" and new data "arc_options". These are the internals for keeping track of options and arguments entries that can easily be extended. 3) To print the options, the "print_arc_disassembler_options ()" has been adjusted to use this dynamically built structure instead of having them hard-coded inside. To see this in effect, one can look into the output of: $ ./binutils/objdump --help ... The following ARC specific disassembler options are... ... include/ChangeLog: * dis-asm.h (disassembler_options_arc): New prototype. opcodes/ChangeLog: * arc-dis.c (arc_option_arg_t): New enumeration. (arc_options): New variable. (disassembler_options_arc): New function. (print_arc_disassembler_options): Reimplement in terms of "disassembler_options_arc".
