* gfortran.h : Add 'use_rename' bit to symbol_attribute.
* module.c : Add 'renamed' field to pointer_info.u.rsym.
(load_generic_interfaces): Add 'renamed' that is set after the
number_use_names is called. This is used to set the attribute
use_rename, which, in its turn identifies those symbols that
have not been renamed.
(load_needed): If pointer_info.u.rsym->renamed is set, then
set the use_rename attribute of the symbol.
(read_module): Correct an erroneous use of use_flag. Use the
renamed flag and the use_rename attribute to determine which
symbols are not renamed.
