[NDS32] Deal with nameless arguments in nds32_function_arg and nds32_function_arg_advance.
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_ARG_ENTIRE_IN_GPR_REG_P): ... this one and ...
(NDS32_ARG_PARTIAL_IN_GPR_REG_P): ... this one.
