dim 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.

  The standard we compile libc++ with is called c++11 not c++0x.

MFC r273066 (by bapt):

MFC r273381 (by bapt):
  Add support for __cxa_throw_bad_array_new_length in libcxxrt

  It is required for use with newer g++49

MFC r273382 (by bapt):
  Fix build by marking the new functions as weak
  This is a temporary fix

MFC r273407 (by bapt):
  When using an external gcc 4.8+ and not building libstdc++ then create in the objectdir a
  fake libstdc++.so and libstdc++.a which is a symlink on libc++ that allow g++ to satisfy
  its links dependencies in the least hackish way.
  Please note that this hacky libstds++ never get installed on the final system

  Do not define bad_array_new_length::bad_array_new_length in libc++ anymore
  when used in combinaison with libcxxrt since it is now defined there already.

MFC r277217:
  Import libc++ trunk r224926.  This fixes a number of bugs, completes
  C++14 support[1], adds more C++1z features[2], and fixes the following
  LWG issues[3]:

  1450: Contradiction in regex_constants
  2003: String exception inconsistency in erase.

	assumptions
  2104: unique_lock move-assignment should not be noexcept
  2112: User-defined classes that cannot be derived from
  2132: std::function ambiguity
  2135: Unclear requirement for exceptions thrown in

  2213: Return value of std::regex_replace
  2240: Probable misuse of term "function scope" in [thread.condition]
  2252: Strong guarantee on vector::push_back() still broken with C++11?
  2257: Simplify container requirements with the new algorithms
  2258: a.erase(q1, q2) unable to directly return q2
  2263: Comparing iterators and allocator pointers with different

  2268: Setting a default argument in the declaration of a member
	function assign of std::basic_string

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.

  Discussed with:	theraven, joerg@netbsd

MFC r278016:
  Import libcxxrt master 1cb607e89f6135bbc10f3d3b6fba1f983e258dcc.

  Interesting fixes:
  1cb607e Correct gcc version check for __cxa_begin_catch() declaration
