[Bug Skip]: [Failed to collect] [Regression] dynamo/test_misc_xpu.py fails to import: cannot import name 'TestTracer' from dynamo.test_misc #6142
Description
🐛 Describe the bug with skip template
Cases:
op_ut,,third_party.torch-xpu-ops.test.xpu.dynamo.test_misc_xpu
Summary
test/xpu/dynamo/test_misc_xpu.py imports TestTracer from the upstream test/dynamo/test_misc.py, which no longer defines that class, so the wrapper raises ImportError during collection and the entire module is lost - the baseline passed 1021 cases in it. The fix is in the XPU wrapper's import list, which has to drop or replace TestTracer. Upstream also removed the other jit-tracing dynamo cases in this same run (test_jit_trace_errors, test_script_function_graph_break and test_tracing_flags_scriptable_dynamic_shapes all appear as vanished), so this is most likely part of the same TorchScript removal as g1 and g2.
ErrorLog
ImportError: cannot import name 'TestTracer' from 'dynamo.test_misc' (/__w/torch-xpu-ops/torch-xpu-ops/pytorch/third_party/torch-xpu-ops/test/xpu/../../../../test/dynamo/test_misc.py)
ImportError while importing test module '/__w/torch-xpu-ops/torch-xpu-ops/pytorch/third_party/torch-xpu-ops/test/xpu/dynamo/test_misc_xpu.py'.
Hint: make sure your test modules/packages have valid Python names.

These test files did not fail their cases - they erased them. A module that will not import reports one row and its cases never run at all.

Same root cause as #6140, #6141, split because the cases do not share a classification or a row shape.
