These tests were marked as failing because the libc implementation does not
use the proper return type on certain math functions. There is other weirdness
that prevents us from defining our own version of these functions.
The failing tests in cmake were separated into their own files so that the rest
failures in the rest of the cmath tests were not hidden.
This was not done for the math.h test since we don't actually supply math.h

Linux has a lot of failures caused by not having support for certain
locales. Since these come out as a lot of noise in the test results,
have lit.cfg detect the presence of the various locales used in the
tests and add them to config.available_features as locale.LOCALE_NAME.
This patch also adds REQUIRES: locale.REQUIRED_LOCALE to every test that
I saw failing in this manner. We probably need to add more for all the
tests requiring en_US.UTF-8, but we can do that on an as-needed basis.
One thing that concerns me is how many tests get skipped because of
missing locales (especially in regex/). We should make a point of
splitting up any tests that test default behavior _and_ behavior under a
given locale so that we aren't losing coverage for default behavior.

Summary: This patch moves the SFINAE for __is_destructor_welformed out of the function template parameters. type_traits must compile in c++03 mode since it is included in c++03 headers.
Test Plan: No tests have been added.

__get_classname() and __bracket_expression were assuming that
char_class_type was ctype_base::mask rather than using
regex_traits<_CharT>::char_class_type.
This change allows char_class_type to be defined to something other than
ctype_base::mask so that the implementation will still work for
platforms with an 8-bit ctype mask (such as Android and OpenBSD).

Pass target name ("cxxabi") to target_link_libraries(cxx ...) to ensure
that linker is able to locate just-built libc++abi in the build tree,
instead of relying on "-lc++abi" linker flag.

This will detect if you are building libcxx in-tree and libcxxabi is
available. If so, it will default to using the in-tree libcxxabi by
setting LIBCXX_CXX_ABI to "libcxxabi", LIBCXX_LIBCXXABI_INCLUDE_PATHS to
"${CMAKE_SOURCE_DIR}/projects/libcxxabi/include" and will add "cxxabi"
as a proper dependency.

Summary: The polymorphic allocator implementation would greatly benefit by defining virtual functions in the dynlib instead of inline. In order to do that some types are going to have to be available outside of c++1y. This is the first step.

Android's ctype implementation comes from openbsd, which for some reason
doesn't consider numbers to be hex digits.

std::make_heap is currently implemented by iteratively applying a
siftup-type algorithm. Since sift-up is O(ln n), this gives
std::make_heap a worst case time complexity of O(n ln n).
The C++ standard mandates that std::make_heap make no more than O(3n)
comparisons, this makes our std::make_heap out of spec.
Fix this by introducing an implementation of __sift_down and switch
std::make_heap to create the heap using it.
This gives std::make_heap linear time complexity in the worst case.
This fixes PR20161.

Summary:
This patch adds the `<experimental/utility>` header as specified in the latest draft of the library fundamentals TS.
`<experimental/utility>` only contains `class erased_type`.
This patch also updates the documentation to list the `erased_type` class as "initial implementation complete".
Test Plan:
Three test cases where added:
1. Test that `_LIBCPP_VERSION` is defined.
2. Test that `<utility>` has been included.
3. Test that `erased_type` is in the correct namespace and is constexpr default constructible.

Mark the base classes for time_get_byname and time_get as _LIBCPP_TYPE_VIS_ONLY
rather than _LIBCPP_TYPE_VIS. These base classes are templated types and cannot
be stored with export dll storage.

time_get_byname classes are used.
