Marshall Clow 76b4afc040 Fix PR#25973 : 'basic_string::assign(InputIt, InputIt) doesn't provide the strong exception safety guarantee'. This turned out to be a pervasive problem in <string>, which required a fair amount of rework. Add in an optimization for when iterators provide noexcept increment/comparison/assignment/dereference (which covers many of the iterators in libc++). Reviewed as http://reviews.llvm.org/D15862

Ahmed Bougacha 812d65a26a [libcxx] Set LC_ALL rather than LC_COLLATE to override collation. 
r251131 replaced LANG with LC_COLLATE. But LC_ALL has precedence
over both, so the test still fails when LC_ALL=C.

Eric Fiselier 831c112954 Fix various GCC mis-configurations for newer versions. 
This patch goes through and enables C++11 and C++14 features for newer GCC's.
The main changes are:

1. Turn on variable templates. (Uses __cpp_variable_templates)
2. Assert atomic<Tp> is trivially copyable (Uses _GNUC_VER >= 501).
3. Turn on trailing return support for GCC. (Uses _GNUC_VER >= 404)
4. XFAIL void_t test for GCC 5.1 and 5.2. Fixed in GCC 6.

Asiri Rathnayake ea4282d336 [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.

Asiri Rathnayake f520c1445f 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.
