[NDS32] No need to take padding into consideration in Andes ABI2 because
we can pass arguments in registers for variadic function.

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
r3 <- 33
r4 <- 44
r5 <- 55
[sp + 0] <- 66
2. Note that we DO NOT handle it for TARGET_HARD_FLOAT case.
The TARGET_HARD_FLOAT should push all the nameless arguments into
stack and GCC is able to take care of them itself.
In addition, we have not implemented hard float on trunk yet.

-- 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.

-- 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.

not use v3push/v3pop on isr and vararg functions.
