Constructing a std::locale object from an empty string selects the language
from the current environment variables. If the environment variables name
a locale that doesn't exist, or isn't installed, then the construction of
facets using that locale may throw.
This patch removes tests that use 'std::locale l("")'.
The optimal solution would be to manually set the environment variables
in the test. Unfortunately there is no portable way to do this.

Use strtof and strtod for floats and doubles respectively instead of
always using strtold. The other parts of the change are already implemented
in libc++.
This patch also has a drive by fix to wbuffer_convert::underflow() which
prevents it from calling memmove(buff, null, 0).

This patch does the following:
* Remove <__config> includes from some container tests.
* Guards uses of std::launch::any in async tests because it's an extension.
* Move "test/std/extensions" to "test/libcxx/extensions"
* Moves various non-standard tests including those in "sequences/vector",
"std/localization" and "utilities/meta".

Commit f49839299a085505eb673544744b61d2d9cdd1db in glibc-2.14 changed the
locales to the currently required format. However, they were again changed in
commit 55bdd2866f23b28422d969060b3518909a12b100 which has been released in 2.17.
That leads to the current situation where Debian and e.g. CentOS 6 have the
pre-2.14 locales, for example Ubuntu 14.04 has pre-2.17 and CentOS 7 on the
other hand has the newest locales in glibc-2.17.

Summary:
These are the tests that didn't fail in the release candidate because they were
covered by another 'REQUIRES' directive.

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.

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 time_put test doesn't seem to work on Linux and CloudABI. For Linux
we already have an XFAIL. Closer inspection seems to reveal that this
test does not pass for a couple of reasons.
First of all, the tm_yday field is set to an invalid value. The
strftime() function doesn't behave consistently across platforms in case
the values in the tm structure are incoherent. Fix up this field to have
the value 121, which corresponds with tm_mday, tm_mon and tm_year. This
of course affects the output of time_put for some modifiers, so update
the tests accordingly.
Second, some of the tests actually use modifiers that are only present
on BSD derived systems. They are not part of the C standard/POSIX.
Simply remove them.
Finally, some of the tests actually use invalid modifiers, causing a
malformed format string to be passed to strftime(). Remove these tests
as well.

This basically reverts the revert in r216508, and fixes a few more cases while
I'm at it. Reading my commit message on that commit again, I think it's bupkis.

Summary:
MSAN and ASAN also replace new/delete which leads to a link error in these tests. Currently they are unsupported but I think it would be useful if these tests could run with sanitizers.
This patch creates a support header that consolidates the new/delete replacement functionality and checking.
When we are using sanitizers new and delete are no longer replaced and the checks always return true.
