New c-torture execute testcase

[Joern Rennecke <amylaar at cygnus dot co dot uk>]

This is modified from 931004-12.c, but by using a struct of size 5,
a lot of different code is executed for typical 32 bit targets -
I was looking for the reason why the MUST_PASS_IN_STACK problem didn't
bite me on the SH as on the d10v, and found out that it was only a matter
of the structure being larger than PARM_BOUNDARY.

#include <stdarg.h>

struct tiny
{
  char c;
  char d;
  char e;
  char f;
  char g;
};

f (int n, ...)
{
  struct tiny x;
  int i;

  va_list ap;
  va_start (ap,n);
  for (i = 0; i < n; i++)
    {
      x = va_arg (ap,struct tiny);
      if (x.c != i + 10)
	abort();
      if (x.d != i + 20)
	abort();
      if (x.e != i + 30)
	abort();
      if (x.f != i + 40)
	abort();
      if (x.g != i + 50)
	abort();
    }
  {
    long x = va_arg (ap, long);
    if (x != 123)
      abort();
  }
  va_end (ap);
}

main ()
{
  struct tiny x[3];
  x[0].c = 10;
  x[1].c = 11;
  x[2].c = 12;
  x[0].d = 20;
  x[1].d = 21;
  x[2].d = 22;
  x[0].e = 30;
  x[1].e = 31;
  x[2].e = 32;
  x[0].f = 40;
  x[1].f = 41;
  x[2].f = 42;
  x[0].g = 50;
  x[1].g = 51;
  x[2].g = 52;
  f (3, x[0], x[1], x[2], (long) 123);
  exit(0);
}
