Extend output format for drcachesim opcode mix

Currently opcodes dumps just names ( bin64/drrun -t drcachesim -simulator_type opcode_mix -indir drmemtrace.*.dir)
And some of opcodes have the same names
for example,
```
Opcode mix tool results:
578415 : total executed instructions
81645 : mov
69303 : mov
55366 : cmp
....
```
Is it useful to add opcode number to define opcode?
I mean output like this
```
Opcode mix tool results:
578415 : total executed instructions
81645 : mov( 56)
69303 : mov( 55)
55366 : cmp( 14)
```
```
