e465ff34be [PATCH] D25483: [libcxx] [test] Fix non-Standard assumptions about how many elements are allocated 
git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@285346 91177308-0d34-0410-b5e6-96231b3b80d8

124ed406e5 [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.

1e5a4a4a71 Fix or move various non-standard tests. 
This patch does the following:

* Remove <__config> includes from some container tests.
* Guards uses of std::launch::any in async tests because it's an extension.
* Move "test/std/extensions" to "test/libcxx/extensions"
* Moves various non-standard tests including those in "sequences/vector",
  "std/localization" and "utilities/meta".

cc2e93cff0 Make it possible to build a no-exceptions variant of libcxx. 
Fixes a small omission in libcxx that prevents libcxx being built when
-DLIBCXX_ENABLE_EXCEPTIONS=0 is specified.

This patch adds XFAILS to all those tests that are currently failing
on the new -fno-exceptions library variant. Follow-up patches will
update the tests (progressively) to cope with the new library variant.
