This adds a hint on where the call trace originated from. This is more of
a guess, but still, it seems to be quite accurate on the traces I tested.
So it appears in the output like:
...
0x06c470c8: 0x780e0002: 3DSTATE_CC_STATE_POINTERS
0x06c470cc: 0x00007f81: blend change 1
0x06c470d0: 0x00007f01: depth stencil change 1
0x06c470d4: 0x00007f41: cc change 1
