Generated by running the following from PyTorch root: ``` find . -regex ".*\.\(cpp\|h\|cu\|hpp\|cc\|cxx\)$" | grep -v "build/" | xargs -n 50 -P 4 perl -pi -e 's/c10::optional/std::optional/' ``` `c10::optional` is just an alias for `std::optional`. This removes usages of that alias in preparation for eliminating it entirely.
