[Bug tree-optimization/41031] [4.5 Regression]: build breakage for cris-elf building newlib, ICE in insert_value_copy_on_edge

The same happens when bootstrapping on s390x while building libdecnumber. Here
is a reduced testcase:

typedef struct
{
  unsigned char bits;
  unsigned short int lsu[1];
} decNumber;

void
decCompareOp (decNumber * res, const decNumber * lhs, unsigned char op)
{
  int result = 0;

  if ((((lhs)->bits & (0x20 | 0x10)) != 0))
    {
      op = 0x02;
      if (lhs->bits & 0x20)
        result = -1;
    }
  if (op == 0x01 || op == 0x06 || op == 0x04)
    {
      if (result != 0)
        *res->lsu = 1;
    }
}
