Marked as reviewed by thartmann (Reviewer).

This changes the output from

PcDesc(pc=0x00007fe00d12475f offset=ffffffff bits=0):
PcDesc(pc=0x00007fe00d12478c offset=2c bits=0):   Test::test3 at -1 (line 33)
``` 
to

PcDesc(pc=0x00007f4fc9035a5f offset=ffffffff bits=0):
PcDesc(pc=0x00007f4fc9035a8c offset=2c bits=0):
   Test::test3 at -1 (line 33)
``` 
But since that is more inline with the output of `ScopeDesc::print_on`, that's fine with me.
