* c-decl.c (duplicate_decls): Break apart into...
(diagnose_arglist_conflict, validate_proto_after_old_defn)

... these new functions. Restructure for comprehensibility.

location of the previous declaration when a diagnostic is issued.
(redeclaration_error_message): Fold into diagnose_mismatched_decls.
(match_builtin_function_types): Delete unnecessary forward declaration.
