[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.

for TARGET_MUST_PASS_IN_STACK.

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.

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.
* config/nds32/nds32.c (nds32_function_arg): Deal with nameless
arguments.
(nds32_function_arg_advance): Deal with nameless arguments.
* config/nds32/nds32.h (NDS32_ARG_PASS_IN_REG_P): Split it into ...

[NDS32] Since argument pointer must be 8-byte alignment, our first parameter may
require 4-byte offset if pushed varargs is not 8-byte aligned.

according to the value of crtl->args.pretend_args_size.
