Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/48160 We no longer use the custom c++ test infra anyways, so move to pure gtest. Fixes #45703 ghstack-source-id: 116977283 Test Plan: `buck test //caffe2/test/cpp/tensorexpr` Reviewed By: navahgar, nickgg Differential Revision: D25046618 fbshipit-source-id: da34183d87465f410379048148c28e1623618553
