Eric Fiselier f2f3637d40 Fix PR27374 - Remove the implicit reduced-arity-extension in tuple.
This patch removes libc++'s tuple extension which allowed it to be
constructed from fewer initializers than elements; with the remaining
elements being default constructed. However the implicit version of
this extension breaks conforming code. For example:

    int fun(std::string);
    int fun(std::tuple<std::string, int>);
    int x = fun("hello"); // ambigious

Because existing code may already depend on this extension it can be re-enabled
by defining _LIBCPP_ENABLE_TUPLE_IMPLICIT_REDUCED_ARITY_EXTENSION.

Note that the explicit version of this extension is still supported,
although it's somewhat less useful than the implicit one.

libc++ Documentation
====================

The libc++ documentation is written using the Sphinx documentation generator. It is
currently tested with Sphinx 1.1.3.

To build the documents into html configure libc++ with the following cmake options:

  * -DLLVM_ENABLE_SPHINX=ON
  * -DLIBCXX_INCLUDE_DOCS=ON

After configuring libc++ with these options the make rule `docs-libcxx-html`
should be available.
