Preparation for the next PR in this stack: #89559.
I replaced
- `self.assertTrue(torch.equal(...))` with `self.assertEqual(..., rtol=0, atol=0, exact_device=True)`,
- the same for `self.assertFalse(...)` with `self.assertNotEqual(...)`, and
- `assert torch.equal(...)` with `torch.testing.assert_close(..., rtol=0, atol=0)` (note that we don't need to set `check_device=True` here since that is the default).
There were a few instances where the result of `torch.equal` is used directly. In that cases I've replaced with `(... == ...).all().item()` while sometimes also dropping the `.item()` depending on the context.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/52658
DCE will reverse iterate over the graph looking for nodes without users and delete them. It will skip over unused placeholders (since this affects the signature of the method) and outputs (which never have users but we want to keep them :) )
Test Plan: Added unit tests
