Distilled testcase (-g -O2):
extern int bar (void);

static int
foo (int x, int y)
{
  if (y)
goto lab;
  if (x)
y = 0;
  if (y)
goto lab;
  y = 0;
lab:
  return y;
}

void
baz (int x, int y)
{
  y = foo (x, y);
  if (y != 0)
bar ();
}

Same problem as PR42166.  I'll add the C testcase as well.

*** This bug has been marked as a duplicate of 42166 ***
