David Majnemer 7ec93f9b1c Implement N3891: A proposal to rename shared_mutex to shared_timed_mutex 
This is as straightforward as it sounds, a renamed from shared_mutex to
shared_timed_mutex.

Note that libcxx .dylib and .so files built with c++14 support need to
be rebuilt.

Marshall Clow ef3d680093 Implement LWG 2360: 'reverse_iterator::operator*() is unimplementable'. Note that this is a (small) behavior change in the library. Reverse iterators whose base iterators' operator* return references to 'within themselves' have been sacrificed to the greater goal of avoiding data races.

Marshall Clow b33d838bcf Final bit for LWG #2263; test different allocator pointer types. Note that libc++ already does the right thing here; I've just added tests to ensure that it stays this way.

Marshall Clow b162b17f05 Implement LWG #2344: quoted()'s interaction with padding is unclear. I think that anyone using quoted with padding is really confused, but it should work the way the rest of iostreams works.

Peter Collingbourne 8845dbd798 Do not derive __gnu_cxx::hash<T> from std::hash<T>. 
Instead, define explicit specializations for the basic types listed in
the SGI documentation. This solves two problems:

 1) Helps avoid silent ODR violations caused by the absence of a
    user-supplied __gnu_cxx::hash specialization in cases where a std::hash
    specialization exists (e.g. for std::string).

 2) __gnu_cxx::hash semantics are slightly different to those of
    std::hash (for example, the former may dereference a pointer argument)
    so it is inappropriate for __gnu_cxx::hash to receive std::hash
    specializations by default.

Marshall Clow 78a87e8a68 Implement LWG 2193. Default constructors for standard library containers are explicit. Note that libc++ already did this for string/deque/forward_list/list/vector and the unordered containers; implement it for set/multiset/map/multimap. Add tests for all the containers. Two drive-by fixes as well: add a missing explicit in <deque>, and remove a tab that snuck into a container test. This issue is also LLVM bug 15724, and resolves it.

Marshall Clow 16da324051 Implement LWG issue 2306: match_results::reference should be value_type&, not const value_type&. This is a general move by the LWG to have the reference type of read-only containers be a non-const reference; however, there are no methods that return a non-const reference to a match_result entry, so there's no worries about getting a non-const reference to a constant object.
