Track the difference between

 -- a constructor list initialization that unpacked an initializer list into
    constructor arguments and
 -- a list initialization that created as std::initializer_list and passed it
    as the first argument to a constructor

in the AST. Use this flag while instantiating templates to provide the right
semantics for the resulting initialization.
