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...
