Minor cleanup for string_view; mostly from suggestions by Richard Smith. Also, make the tests pass under c++03

Fix some failing tests for the standard containers. The tests were failing in 32-bit mode because they assumed that std::size_type and make_unsigned<ptrdiff_t>::type were always the same type. No change to libc++, just the tests.

string_view enhancements. Move to the correct namespace. Better constexpr support (thanks to Richard for the suggestions). Update the tests to match this. Add <experimental/__config for experimental macros/etc to live.

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.
