[NDS32] No need to take padding into consideration in Andes ABI2 because

  1. We have caller prepare nameless arguments in the way of calling a normal function.

     e.g. Assume a function: void va_test (int n, ...);
          When calling "va_test (6, 11, 22, 33, 44, 55, 66);",
               r0    <- 6
               r1    <- 11
               r2    <- 22

[NDS32] We need to make sure it is NOT a variadic function so that some v3push/v3pop preparation can be applied.

  -- The rationale of such avoidance is that the 'pop25' instruction also
     contains return behavior and we have no chance to further adjust stack
     pointer before returning to caller, which is very important to
     variadic function.
  -- So we do not setup v3push/v3pop (push25/pop25) information for a
     variadic function.  It will use normal stack push/pop instead.

	* config/nds32/nds32.c (nds32_compute_stack_frame): Do not use
	v3push/v3pop for variadic function.

From-SVN: r214857

  -- In fact, we only need to take care of 'push.s' situation,
     because we have to push all the nameless arguments into stack.
  -- We do not have to use 'pop.s' to restore them back to registers,
     because we can just adjust stack pointer to set frame location.
     This operation should be done in epilogue expanding.
  -- Because 'pop25' instruction also performs return operation, we will
     not use v3push/v3pop on isr and vararg functions.
     Therefore, their instruction length should be 4 bytes.
