Stephan T. Lavavej 03fe6e2da2 [libcxx] [test] Fix Clang -Wunused-local-typedef, part 1/3.
Guard typedefs and static_asserts with _LIBCPP_VERSION.

test/std/containers/sequences/vector.bool/move_assign_noexcept.pass.cpp
test/std/containers/sequences/vector.bool/move_noexcept.pass.cpp
test/std/containers/sequences/vector.bool/swap_noexcept.pass.cpp
Additionally deal with conditional compilation.

test/std/containers/associative/map/map.cons/move_noexcept.pass.cpp
test/std/containers/associative/multimap/multimap.cons/move_noexcept.pass.cpp
Additionally deal with typedefs used by other typedefs.

Fixes D29135.

Stephan T. Lavavej 286adee501 [libcxx] [test] Fix MSVC x64 truncation warnings with 32-bit allocator size_type/difference_type.
test/std/containers/container.adaptors/queue/queue.cons.alloc/ctor_container_alloc.pass.cpp
test/std/containers/container.adaptors/stack/stack.cons.alloc/ctor_container_alloc.pass.cpp
Iterate with C::size_type because that's what operator[] takes.

test/std/containers/sequences/vector/contiguous.pass.cpp
test/std/strings/basic.string/string.require/contiguous.pass.cpp
Add static_cast<typename C::difference_type> because that's what the iterator's operator+ takes.

Fixes D27777.

Stephan T. Lavavej e898b484f6 [libcxx] [test] D27013: Fix MSVC warning C4018 "signed/unsigned mismatch", part 1/12.
Change loop indices from int to std::size_t.

Also, include <cstddef> when it wasn't already being included.

Eric Fiselier 69a4f66114 [libc++] Fix stack_allocator
Summary:
To quote STL the problems with stack allocator are"

>"stack_allocator<T, N> is seriously nonconformant to N4582 17.6.3.5 [allocator.requirements].
> First, it lacks a rebinding constructor. (The nested "struct rebind" isn't sufficient.)
> Second, it lacks templated equality/inequality.
> Third, it completely ignores alignment.
> Finally, and most severely, the Standard forbids its existence. Allocators are forbidden from returning memory "inside themselves". This requirement is implied by the Standard's requirements for rebinding and equality. It's permitted to return memory from a separate buffer object on the stack, though."

This patch attempts to address all of those issues.

First, instead of storing the buffer inside the allocator I've change `stack_allocator` to accept the buffer as an argument.

Second, in order to fix rebinding I changed the parameter list from `<class T, size_t NumElements>` to `<class T, size_t NumBytes>`. This allows allocator rebinding
between types that have different sizes. 

Third, I added copy and rebinding constructors and assignment operators.

And finally I fixed the allocation logic to always return properly aligned storage.
