7b7c9ec355 LWG#2156 loosened the requirements on unordered containers 'rehash' calls. Add tests to make sure we meet these requirements. Since we met the stricter ones, no code change needed to meet the looser ones.

94d9b1c5b2 [libcxx] Fixup a few fumbles in the initial no-exceptions XFAILs list. 
The initial buildbot run found a few missing bits in the initial XFAIL list
for the no-exceptions libc++ variant. These discrepancies are as follows:

[1] Following two tests need XFAILs on the no-exceptions library variant.
My local runs had these two disabled for other reasons (unsupported):

  - localization/locales/locale/locale.cons/char_pointer.pass.cpp
  - numerics/complex.number/complex.ops/complex_divide_complex.pass.cpp

[2] These three does not need XFAILs, they were failing on my local runs for
other reasons:

  - depr/depr.c.headers/uchar_h.pass.cpp
  - input.output/iostreams.base/ios/basic.ios.members/copyfmt.pass.cpp
  - .../category.collate/locale.collate.byname/transform.pass.cpp

(these are failing on my box for the default build as well)

The current patch fixes both the cases above. Additionally, I've run the
following scan to make sure I've covered all the cases:

> grep ' catch \| try \| throw ' -R . | perl -pe 's|(.*?):.*|\1|' | sort | \
  uniq > 1.txt
> grep 'libcpp-no-exceptions' -R . | perl -pe 's|(.*?):.*|\1|' | sort | \
  uniq > 2.txt
> diff 1.txt 2.txt

This showed up a few extra interesting cases:

[3] These two tests do not use try/catch/throw statements, but they fail at
runtime. Need to be investigated, I've left the XFAILs in.

  - std/thread/futures/futures.shared_future/dtor.pass.cpp
  - std/thread/futures/futures.unique_future/dtor.pass.cpp

[4] These tests use a macro named TEST_HAS_NO_EXCEPTIONS to conditionally
exclude try/catch/throw statements when running without exceptions. I'm not
entirely sure why this was needed (AFAIK, we didn't have a no-exceptions
library build before). The macro's defintion is quite similar to that of
_LIBCPP_NO_EXCEPTIONS. I will investigate if this can be reused for my test
fixes or if it should be replaced with _LIBCPP_NO_EXCEPTIONS.

cc2e93cff0 Make it possible to build a no-exceptions variant of libcxx. 
Fixes a small omission in libcxx that prevents libcxx being built when
-DLIBCXX_ENABLE_EXCEPTIONS=0 is specified.

This patch adds XFAILS to all those tests that are currently failing
on the new -fno-exceptions library variant. Follow-up patches will
update the tests (progressively) to cope with the new library variant.

the test tries to impose and the test fails.

b3b00818e5 Fix use of libc++ <foo.h> headers from within an 'extern "C"' context in C++98. 
Previously, this resulted in us declaring a template for static_assert emulation within the 'extern "C"' context, which is ill-formed.

759cd0e86b Split <stddef.h> out of <cstddef>. 
There are a bunch of macros (__need_size_t etc) that request just one piece of
<stddef.h>; if any one of these is defined, we just directly include the
underlying header.

Note that <stddef.h> provides a ::nullptr_t. We don't want that available to
includers of <cstddef>, so instead of following the usual pattern where <cfoo>
includes <foo.h> then pulls things from :: into std:: with using-declarations,
we implement <stddef.h> and <cstddef> separately; both include <__nullptr> for
the definition of std::nullptr_t.
