5e64cfa6 - Make TensorName::unifyFromRight in-place for efficiency (#29307)

Make TensorName::unifyFromRight in-place for efficiency (#29307) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/29307 In our name inference functions we currently create an extra TensorNames every time we unify names. This isn't completely necessary. To do this, I made the following changes: - TensorName now has two states, initialized and uninitialized - Renamed unifyFromRight to unifyFromRightInplace. Test Plan: - `pytest test/test_namedtensor.py -v` Differential Revision: D18453388 Pulled By: zou3519 fbshipit-source-id: 96c3c6fd9478d57e92e1cf770c864aeac6d29dd2
