Implement the resolution of LWG2993. Replace a deleted constructor with a constructor that SFINAEs away in appropriate circumstances. Also, now that the constructor is templated, we must have an explicit deduction guide to make CTAD work. Some tests have been merged in from Agustín Bergé's D40259.

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.
