[SDAG] Use correct alignments on expanded vector trunc-store/ext-loads

When expanding a truncating store or extending load using vector extracts or
inserts and scalar stores and loads, we were giving each of these scalar stores
or loads the same alignment as the original vector operation. While this will
often be right (most vector operations, especially those produced by

Summary:
Currently parts of the SFINAE on tuples default constructor always gets evaluated even when the default constructor is never called or instantiated. This can cause a hard compile error when a tuple is created with types that do not have a default constructor. Below is a self contained example using a pair like class. This code will not compile but probably should.

```

#include <type_traits>

template <class T>
struct IllFormedDefaultImp {
    IllFormedDefaultImp(T x) : value(x) {}
    constexpr IllFormedDefaultImp() {}
    T value;
};

typedef IllFormedDefaultImp<int &> IllFormedDefault;

template <class T, class U>
struct pair
{
  template <bool Dummy = true,
    class = typename std::enable_if<
         std::is_default_constructible<T>::value
      && std::is_default_constructible<U>::value
      && Dummy>::type
    >
  constexpr pair() : first(), second() {}

  pair(T const & t, U const & u) : first(t), second(u) {}

int main()
{
  int x = 1;
  IllFormedDefault v(x);
  pair<IllFormedDefault, IllFormedDefault> p(v, v);
}
```

One way to fix this is to use `Dummy` in a more involved way in the constructor SFINAE. The following patch fixes these sorts of hard compile errors for tuple.
