Two minor 2.4 FPs

[Dan Workman]

Just upgraded to 2.4 and have found two minor False Positives

The first thinks that zero-initialization of a std::array will empty it and the other claims that a variable is uninitialized even though it is not (I admit the usage is rather odd)

void fp_1()
{
  std::array<int, 4> a = {};
  std::cout << a[0]; // warning: Out of bounds access in expression 'a[0]' because 'a' is empty. [containerOutOfBounds]
}

void fp_2()
{
  std::stringstream ss("1 2 3 4");

  for (int i; ss >> i;) // warning: Uninitialized variable: i [uninitvar]
    std::cout << i;
}

The first FP should be covered by this.

Second ticket is here.
