This builds on the work done in r342808 and adds _LIBCPP_NODISCARD_EXT to 37 more functions, namely: adjacent_find, all_of, any_of, binary_search, clamp, count_if, count, equal_range, equal, find_end, find_first_not_of, find_first_of, find_if, find, includes, is_heap_until, is_heap, is_partitioned, is_permutation, is_sorted_until, is_sorted, lexicographical_compare, lower_bound, max_element, max, min_element, min, minmax_element, minmax, mismatch, none_of, remove_if, remove, search_n, search, unique, upper_bound The motivation here is that we noticed that find_if is nodiscard with Visual Studio's standard library, and we deemed that useful (https://crbug.com/948122). https://devblogs.microsoft.com/cppblog/c17-progress-in-vs-2017-15-5-and-15-6/ says "Our criteria for emitting the warning are: discarding the return value is a guaranteed leak [...], discarding the return value is near-guaranteed to be incorrect (e.g. remove()/remove_if()/unique()), or the function is essentially a pure observer (e.g. vector::empty() and std::is_sorted())." so I went through algorithm and tried to apply these criteria. Some of these, like vector::empty() are already nodiscard per C++ standard and didn't need changing. I didn't (yet?) go over std::string::find* methods which should probably have _LIBCPP_NODISCARD_EXT too (but not as part of this change).

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.
