[Bug optimization/14770] redundant store due to the fact that implicit set is not noticed

Confirmed, even without saying foo(0) aka writing foo (a):
void foo (int);

void
bar (int a)
{
  if (!a)
    foo (a);
}
Gives the same asm which is worse than before as we had said that the variable should 
not change.
