Fix missing filename and line number in warning
When the 'bin_opt_info' is given, warnings without filenames and line numbers could sometimes be produced: no_file: Warning: INFO: matching non-variables after a previous clause matching a variable will prevent delayed sub binary optimization The reason for the missing information is that #c_alias{} records lack location information. There are several ways to fix the problem. The easiest seems to be to get the location information from the code). Noticed-by: José Valim
