Summary: `inspect.stack()` calls are slow since they access a bunch of extra info about the frame. This PR instead uses `inspect.currentframe()` and goes up the stack until it reaches the correct frame. [Context](stackoverflow.com/questions/17407119/python-inspect-stack-is-slow) Pull Request resolved: pytorch#12859 Differential Revision: D10509912 Pulled By: driazati fbshipit-source-id: b85325adf1b3c85a1a3a82e96e567b8be498531b
