Mark the base classes for time_get_byname and time_get as _LIBCPP_TYPE_VIS_ONLY
rather than _LIBCPP_TYPE_VIS. These base classes are templated types and cannot
be stored with export dll storage.
Fixes compilation with _LIBCPP_DLL for Windows when the time_get and
time_get_byname classes are used.

libc++ currently relies on undefined initialization order of global
initializers when using gcc:
1. __start_std_streams in iostream.cpp calls locale:🆔:_init, which assigns
an id to each locale::facet in an initializer
2. Every facet has a static locale::id id, whose constructor sets the facet's
id to 0
If 2 runs after 1, it clobbers the facet's assigned consecutive id, causing
exceptions to be thrown when e.g. running code like "cout << endl".
To fix this, let _LIBCPP_CONSTEXPR evaluate to "constexpr" instead of nothing
with gcc. locale::id's constructor is marked _LIBCPP_CONSTEXPR, which ensures
that it won't get an initializer that could potentially run after the
iostream.cpp initializer. (This remains broken when building with msvc.)
Also switch constexpr-specific code in bitset to use __SIZEOF_SIZE_T__ instead
of __SIZE_WIDTH__, because gcc doesn't define the latter.
Pair-programmed/debugged with Dana Jansens.

(clang doesn't complain about this, but gcc does. This is necessary for a
follow-up patch that will enable _LIBCPP_CONSTEXPR for gcc.)

r207606 changed the __need_foo macros to behave like they do with gcc: If they
are set, _only_ the __need_foo stuff gets defined. As a consequence, cstddef
no longer defined "offsetof". It looks like the __need_foo defines aren't
needed anymore, so just remove them.
Fixes PR19723.

compatibility to libstdc++. Move the implementation into a header for
easier sharing with libc++abi. Merge a number of improvements from that
version. Provide a POD definition for <stdexcept>'s public use to avoid
cast dances. Discussed with Marshall Clow.

libc++ will not call address_sanitizer to detect addressing errors in the
standard library containers. This is a negative macro to enable users to
disable the libc++ checks even if they are compiling with address sanitizer
enabled by defining this macro.
At the present time, there is no code in libc++ that looks at this macro.
That will come soon. This is just infrastructure.

It's identical to name() these days. (At one point it avoided masking
of the RTTI uniqueness bit because ARM64 ignored it architecturally,
but no longer).

ARM64 generates RTTI with hidden visibility, which means that typeinfo
must be compared char-by-char since it's not guaranteed to be uniqued
across the whole program.

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.

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.
