Change Windows decoration on some base classes

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.

Fixes compilation with _LIBCPP_DLL for Windows when the time_get and
time_get_byname classes are used.

[libcxx] Add <experimental/utility> header for LFTS. 

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.

Fix bug #20335 - memory leak when move-constructing a string with unequal allocator. Thanks to Thomas Koeppe for the report

In response to bug #20362, change the order of operations in vector move assignment so that if the allocator move assignment throws, we aren't left with two objects pointing at the same memory. This is not a complete fix; I am unconvinced that a complete fix is possible. With this change in place, we will leak the old contents of the vector. LWG issue #2106, when adopted, will make this problem illegal. Thanks to Thomas Koeppe for the report and analysis.

Fix std::make_heap's worst case time complexity

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.

[libcxx] expose experimental::erased_type for all standard versions.

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.

Better defaults for in-tree libc++ with cmake.

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.

Patch by Russell Harmon.
