* gfortran.h (gfc_use_list): Add where field.
* module.c (use_locus): New static variable.
(gfc_match_use): Set it.
(gfc_use_module): Copy it to gfc_use_list's where field.
* trans-decl.c (gfc_generate_module_vars): Call gfc_trans_use_stmts.
(gfc_trans_use_stmts): Set backend locus before calling the debug
hook. Allow non-VAR_DECLs to be created even for non-external
module. Don't emit anything so far for renames from different
modules.
