Replace throw_exception with throw in some cases

This replaces throw_exception with "throw;" when possible.  This was
written by script.  The rule that is followed is that uses of the
form:

   catch (... &name)
     {
       ...
       throw_exception (name);
     }

... can be rewritten.  This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the
body of the catch.
