[Bug c/36390] New: Unused variable warning should be more useful

["jmfo1982 at yahoo dot es" <gcc-bugzilla at gcc dot gnu dot org>]

gcc and g++ (all the versions I've ever used) don't give unused variable
warnings in a lot of cases where there are unused variables. Simple sample
code:

int test1 ()
{
  int x = 3;
  return (2);
}

int test2 ()
{
  int x;
  x = 3;
  return (2);
}

They only give an unused variable warning in test1 function. They should warn
in both cases.
