Summary: Update the API to access grad in cpp to avoid unexpected thread safety issues. In particular, with the current API, a check like `t.grad().defined()` is not thread safe. - This introduces `t.mutable_grad()` that should be used when getting a mutable version of the saved gradient. This function is **not** thread safe. - The `Tensor& grad()` API is now removed. We could not do a deprecation cycle as most of our call side use non-const Tensors that use the non-const overload. This would lead to most calls hitting the warning. This would be too verbose for all the users.

C++ Frontend Tests
In this folder live the tests for PyTorch's C++ Frontend. They use the GoogleTest test framework.
CUDA Tests
To make a test runnable only on platforms with CUDA, you should suffix your
test with _CUDA, e.g.
TEST(MyTestSuite, MyTestCase_CUDA) { }
To make it runnable only on platforms with at least two CUDA machines, suffix
it with _MultiCUDA instead of _CUDA, e.g.
TEST(MyTestSuite, MyTestCase_MultiCUDA) { }
There is logic in main.cpp that detects the availability and number of CUDA
devices and supplies the appropriate negative filters to GoogleTest.
Integration Tests
Integration tests use the MNIST dataset. You must download it by running the following command from the PyTorch root folder:
$ python tools/download_mnist.py -d test/cpp/api/mnist
The required paths will be referenced as test/cpp/api/mnist/... in the test
code, so you must run the integration tests from the PyTorch root folder.
