[ros-diffs] [greatlrd] 25448: adding blr opcode (can not found it in the ibm or motorala doc, the primary opcode refens to addi). now we can disambler two opcode the li and blr, add blr to my own asm langues.

Log:
adding blr opcode (can not found it in the ibm or motorala doc, the primary opcode refens
to addi). 
now we can disambler two opcode the li and blr, add blr to my own asm langues.
