For me, it is necessary. We need disassemble target binary instructions
(recognize them), then translate them into tcg instructions which are
grouped by Translate Block.

We may not need to display the instructions (it is only for test), but
we still need recognize them.

And for me, current tilera opcode implementation in binutils/kernel is
already almost the fewest and the simplestkk.

OK, thanks, for me, it is a useful tool.
