I'm not sure we want to add these.  You'll need feedback from net/OWNERS.

I'll pull it out for now. Should I be concerned about folks writing error_code
!= net::OK when they really mean (error_code != net::OK && error_code !=
net::ERR_IO_PENDING)?

+  return IsSuccess(error) || error == ERR_IO_PENDING;
