Add ability to compare skips/xfails against a text file of operators
When I run against a list of DPER ops I get this list:
```
aten.count_nonzero.dim_IntList
aten.count_nonzero.default
aten.empty.memory_format # SKIP
aten.repeat_interleave.Tensor
aten.relu.default
aten.nonzero.out
aten.nonzero.default
```
