Pull in r233552 from upstream libc++ trunk (by Eric Fiselier):

  [libcxx] Fix PR22771 - Support access control SFINAE in the library
  version of is_convertible.

  Summary:
  Currently the conversion check does not take place in a context where
  access control SFINAE is applied. This patch changes the context of
  the test expression so that SFINAE occurs if access control does not
  permit the conversion.

3678f64ad3 Synchronize the default C++ stack in stable/10 with head, by merging
almost all recent changes to libc++ and libcxxrt.

MFC r256642:
  Since C++ typeinfo objects are currently not guaranteed to be merged at
  runtime by the dynamic linker, check for their equality in libcxxrt by
  not only comparing the typeinfo's name pointers, but also comparing the
  full names, if necessary.  (This is similar to what GNU libstdc++ does
  in its default configuration.)  The 'deep' check can be turned off again
  by defining LIBCXXRT_MERGED_TYPEINFO, and recompiling libcxxrt.

MFC r277944:
  Partially revert r273382, to reduce diffs against upstream.  This was a
  temporary fix to solve a conflict with an older version of libc++, and
  it is no longer relevant.

MFC r278010:
  Revert r256642, not only to reduce diffs against upstream libcxxrt, but
  also because it is the wrong approach: comparing typeinfo names deeply
  causes trouble if two loaded DSOs use independent types of the same
  name.

  In addition, this particular change was never merged to FreeBSD 10.x and
  9.x, so let's get rid of it before it ends up in an 11.x release.

MFC r261801:

An ABI incompatibility crept into the libc++ 3.4 import in r261283.  It
was caused by upstream libc++ commit r194536, which aimed to make the
headers more standards-compliant, by making std::pair's copy constructor
trivial.  Unfortunately, this could cause certain C++ applications using
shared libraries built against the previous version of libc++ to crash.

Fix the ABI incompatibility by making std::pair's copy constructor
non-trivial again.

Please note: Any C++ applications or shared libraries built with libc++
between r261283 and this revision should be recompiled.

efc7663168 Pull in r168610 from upstream libc++:
When using libc++ headers on FreeBSD, in combination with -std=c++98,
  -ansi or -std=c++03, the long long type is not supported.  So in this
  case, several functions and types, like lldiv_t, strtoll(), are not
  declared.

This should make it possible to use the libc++ headers in c++98 mode.

Note: libc++ is originally designed as a c++0x or higher library, so you
should still take care when using it with c++98 or c++03.
