[Bug middle-end/19551] [3.4/4.0 Regression] LAPACK routine claic1.f bug

Simplified testcase:
extern void abort ();

__attribute__((pure)) _Complex float
foo (int x)
{
  _Complex float r;
  __real r = x + 1;
  __imag r = x - 1;
  return r;
}

void
bar (float *f)
{
  *f = foo (5);
}

int
main (void)
{
  float f;
  bar (&f);
  if (f != 6.0)
    abort ();
  return 0;
}

Likely the culprit is in libcall_dead_p.
