When a statement has no vuses, but its LHS value handle has vuses, we wind
up with
tree val = vn_lookup_or_add_with_stmt (newt, stmt);
vn_add (lhs, val);
Now the LHS value handle changes from vuses to no vuses since the statement
has no vuses. Are you sure you handle this case correctly? Can we reuse
LHS value handle in this case?
