[Bug optimization/13564] New: if-conversion not agressive enough

[kazu at cs dot umass dot edu]

bar could be optimized to baz.
current mainline uses a jump for bar,
but baz uses setcc

void foo (int);

int
bar (int a)
{
  if (a)
    foo (1);
  else
    foo (0);
}

int
baz (int a)
{
  foo (!!a);
}
