Const qualify __mem_fn call operator

  QOI improvement.

  Differential Revision: http://llvm-reviews.chandlerc.com/D2059

5c48f599e6 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.

5830d897a4 Apply a cleaner solution for the sign warnings that can occur when 
compiling libc++'s <locale> header with -Wsystem-headers on.

This has also been submitted upstream.

dd147a8455 In libc++'s type_traits header, avoid warnings (activated by our use of 
-Wsystem-headers) about potential keyword compatibility problems, by
adding a __libcpp prefix to the applicable identifiers.

Upstream is still debating about this, but we need it now, to be able to
import clang 3.4.

43f25c3919 Fix warnings from newer clang versions about constexpr member functions 
not being implicitly const in libc++'s <chrono> header.  The warnings
have been introduced because of new language rules recently adopted by
the C++ WG.  More info:

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.

708d8e446e Import libc++ trunk r165949. Among other improvements and bug fixes, 
this has many visibility problems fixed, which should help with
compiling certain ports that exercise C++11 mode (i.e. Firefox).

Also, belatedly add the LICENSE.TXT and accompanying CREDITS.TXT files,
which are referred to in all the source files.

ad5598305f Import libc++ / libcxxrt into base. Not build by default yet (use 
MK_LIBCPLUSPLUS=yes to enable).  This is a work-in-progress.  It works for
me, but is not guaranteed to work for anyone else and may eat your dog.

To build C++ using libc++, add -stdlib=libc++ to your CXX and LD flags.

Bug reports welcome, bug fixes even more welcome...
