[Bug target/14625] tail call optimization missed

[steven at gcc dot gnu dot org]

FWIW we don't emit the tail call because of this: 
 
      /* If this function requires more stack slots than the current 
         function, we cannot change it into a sibling call.  */ 
      || args_size.constant > current_function_args_size 
 
args_size.constant == 8 (2 ints) and current_function_args_size == 0 
because nothing gets passed on the stack.
