An alias template using the new template template auto deduction would make `integral_constant` slightly easier to use.

[2017-07 Toronto Thurs Issue Prioritization]

Duplicate of 2922.

Proposed resolution:

This wording is relative to N4618.

1. Add to the synopsis of `<type_traits>`:

   >     template <auto N>
   >     using integer_constant = integral_constant<decltype(N), N>;
