Marshall Clow 17af2f56ab Add tests for LWG issue #2356. Stability of erasure in unordered associative containers. Libc++ already does this, but now we have tests for it.

Marshall Clow 988a4e8d0e More tests for LWG Issue #2263; this time to the associative and unordered containers. Still no changes to libc++

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 06965c1fd0 Per N3924, mark random_shuffle as deprecated in the synopsis for <algorithm>. Since we don't actually do anything when a call is deprecated, there is no functionality change. Maybe someday, we'll decide to warn when using a deprecated function.

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.

Error 1 error C2681: 'add_rvalue_reference<_Tp*>::type' : invalid expression
type for dynamic_cast c:\libcxx\include\type_traits

This is one more step getting libcxx compile under Visual C++. The patch is 
#if defined(_LIBCPP_MSVC) so will affect only this build.

When libcxx can be compiled, it will probably require the current version or
maybe even the next Update of Visual C++ 2013.

Chandler Carruth 265b83a87f Teach libc++ to use the compiler-provided C-compatible ::max_align_t 
rather than its own type for std::max_align_t. This is particularly
relevant as the types may not be ABI compatible despite users expecting
them to be.

Yaron Keren 3ef24c4f9a This solves warning C4005: '_NOEXCEPT' : macro redefinition when compiling 
with Visual C++ 2013 by making libcxx definition text-identical to yvals.h.

Persumably this definition is for older Visual C++ versions. 
In such cases it will still be defined so no functionality change.

Other platforms should not be affected as this is inside
