[Bug middle-end/44321] attribute warn_unused_result fails under inlining.

You can add

void bar4 (void)
{
  int dummy;
  dummy = foo ();
}

so I'm not sure the ignore_value () function call isn't a use.  In fact
if you externalize that function it is at least a possible use.

Which also raises the question whether (void) is really more "ignoring"
the result than the assignment to a dummy variable.
