Eric Fiselier c1d527d3d8 Fix PR30260 - optional<const T> not working. 
This patch fixes PR30260 by using a (void*) cast on the placement argument
to placement new to casts away the const. See also http://llvm.org/PR30260.

As a drive by change this patch also changes the header guard for
<experimental/optional> to _LIBCPP_EXPERIMENTAL_OPTIONAL from _LIBCPP_OPTIONAL.

Marshall Clow d437fa5c8c Add an _LIBCPP_NORETURN inline function named __throw_XXX for each exception type we define. They either construct and throw the exception, or abort() (if exceptions are disabled). Use these functions everywhere instead of assert()ing when exceptions are disabled. WARNING: This is a behavior change - but only with exceptions disabled. Reviewed as: https://reviews.llvm.org/D23855.

Marshall Clow e61fba3b70 Add all the relational operators to std::experimental::optional. Also update bad_optional_access to match the Library Fundamentals draft standard. This is not all of the upcoming changes to optional, though.

Marshall Clow aedfb87089 Change the comment on the closing #endif to match the condition on the corresponding #ifdef. Thanks to K-ballo for the catch. No functionality change.

Eric Fiselier c1bd9197eb NFC. Move definition of _LIBCPP_ASSERT into __debug header and remove external include guards. 
Things done in this patch:

1. Make __debug include __config since it uses macros from it.

2. The current method of defining _LIBCPP_ASSERT is prone to redefinitions. Move
the null _LIBCPP_ASSERT definition into the __debug header to prevent this.

3. Remove external <__debug> include gaurds. <__debug> guards almost all of its
contents internally. There is no reason to be doing it externally.

This patch should not change any functionality.

Marshall Clow dfdac03c8f Move <optional> into include/experimental, and into the std::experimental namespace, since it's not part of C++14, but of an upcoming TS
