17e52004 - use irange for loops 8 (#66743)

use irange for loops 8 (#66743) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/66743 Modified loops in files under fbsource/fbcode/caffe2/ from the format `for(TYPE var=x0;var<x_max;x++)` to the format `for(const auto var: irange(xmax))` This was achieved by running r-barnes's loop upgrader script (D28874212) with some modification to exclude all files under /torch/jit and a number of reversions or unused variable suppression warnings added by hand.
