Deduction guides for containers should not participate in overload resolution when called with certain incorrect types (e.g. when called with a template argument in place of an `InputIterator` that doesn't qualify as an input iterator). Similarly, class template argument deduction should not select `unique_ptr` constructors that take a a pointer. The tests try out every possible incorrect parameter (but never more than one incorrect parameter in the same invocation). Also add deduction guides to the synopsis for associative and unordered containers (this was accidentally omitted from [D112510](https://reviews.llvm.org/D112510)).

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. The documentation in this directory is published at https://libcxx.llvm.org. It is kept up-to-date by a build bot: https://lab.llvm.org/buildbot/#/builders/publish-sphinx-docs. If you notice that the documentation is not updating anymore, please contact one of the maintainers.
