... and 34 more tests

Steps to Reproduce:
1. Pull PyTorch at commit e9dfc90
2. Run the test:

python test/run_test.py -i inductor/test_cpu_select_algorithm.py

3. Observe test failures in TestSelectAlgorithmCPU

Expected Result:
All tests in TestSelectAlgorithmCPU should pass

Actual Result:
44 test(s) failing in TestSelectAlgorithmCPU on CPU, sGPU
