SFINAE out duration converting constructor if the constructor would otherwise cause a ratio compile-time overflow.  This fixes LWG 2094.

 - The lit builtin XFAIL handling is more restrictive than what we were
   previously using, and for now I'd rather keep the lit one restrictive.

is_destructible for function types was mistakenly returning true instead of false.  This is true in both C++11 and C++1y, but has been clarified by the post C++11 LWG issue 2049.

Turn off extern templates for most uses.  It is causing more problems than it is worth.  The extern templates will still be built into the dylib, mainly for ABI stability purposes.  And the client can still turn these back on with a #define if desire.  This fixes http://llvm.org/bugs/show_bug.cgi?id=17027.  However there's no associated test for the test suite because http://llvm.org/bugs/show_bug.cgi?id=17027 needs mismatched dylib and headers to fire.

LWG issues 2174/5/6 - mark wstring_convert::converted as noexcept, and make (some of) the constructors for wstring_convert and wbuffer_convert as explicit. Add configuration macro _LIBCPP_EXPLICIT_AFTER_CXX11

Remove _LIBCPP_DEBUG.  This was my first attempt at debug mode for libc++, and is now obsoleted by _LIBCPP_DEBUG2 (which isn't finished).

Debug mode for string.  This commit also marks the first time libc++ debug-mode has found a bug (found one in regex).  Had to play with extern templates a bit to get this to work since string is heavily used within libc++.dylib.

Zhihao Yuan noted that there were a few unneeded  statements.  Eliminated the unnecessary ones, and commented the ones that are there for non-obvious reasons such as to help things limp along in C++03 language mode.

Zhihao Yuan noted that a move assignment operation was missing from std::adjacent_difference.  Fixed.

David Blaikie suggested this test for detecting constexpr on the error_category default constructor.  Additionally I decided to make this constructor trivial as well, as I could not come up with a rationale for not doing so.  Fully tested with both current Apple clang and tip-of-trunk clang.
