Summary:
Make the following changes:
- When there are more than 10k errors, cuda-memcheck only shows 10k errors, in this case we shouldn't raise an Exception
- Add UNDER_CUDA_MEMCHECK environment to allow disabling `pin_memory` tests when running cuda-memcheck.
- Add a `--ci` command option, when turned on, then this script would run output to stdout instead of writing a file, and exit with an error if cuda-memcheck fails
- Add a `--nohang` command option. When turned on, then hang would be treated as pass instead of error
- Do simple filtering on the test to run: if `'cpu'` in the test name but not `'cuda'` is not in the test name
- Add `--split` and `--rank` to allowing splitting the work (NVIDIA CI has a limitation of 3 hours, we have to split the work to satisfy this limitation)
- The error summary could be `ERROR SUMMARY: 1 error`, or `ERROR SUMMARY: 2 errors`, the tail could be `error` or `errors`, it is not of the same length. The script is fixed to handle this case.
- Ignore errors from `cufft`
