separate option for FE_OVERFLOW (#20476)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/20476
There're overflow exceptions happening for legitimate computation like
for big x, sigmoid(x) = 1 / (1 + exp(-x)) = 1 / (1 + inf) = 1
This diff separates the option for FE_OVERFLOW to make caffe2_operator_throw_if_fp_exceptions=1 option less noisy.
