[NDS32] No need to take padding into consideration in Andes ABI2 because
we can pass arguments in registers for variadic function.
-- By default GCC uses must_pass_in_stack_var_size_or_pad for TARGET_MUST_PASS_IN_STACK.
For Andes ABI2, the data layout in memory will be incorrect when calling variadic function
under big-endian configuration.
* config/nds32/nds32.c (nds32_must_pass_in_stack): New implementation
for TARGET_MUST_PASS_IN_STACK.
[NDS32] Provide TARGET_ARG_PARTIAL_BYTES so that we can have structure argument
partially in registers and stack.
-- This is needed if we would like to pass variadic arguments via registers
that are pused on the stack by callee. So that va_arg() can access
arguments continously in memory.
* config/nds32/nds32.c (nds32_arg_partial_bytes): New implementation
for TARGET_ARG_PARTIAL_BYTES.
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.

arguments.

(NDS32_ARG_ENTIRE_IN_GPR_REG_P): ... this one and ...
(NDS32_ARG_PARTIAL_IN_GPR_REG_P): ... this one.
[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.

[NDS32] Consider varargs situation when creating stack operation assembly code.
-- 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.
