Marshall Clow c3deeb5f89 Found six (nmostly) identical files named 'test_allocator.h' in the libcxx test suite. Moved one to /support, made it a superset, and removed all but one of the others, and iupdated all the includes. Left the odd one (thread/futures/test_allocator.h) for later.

Howard Hinnant ccad8c32e0 This fixes a very subtle ABI problem concerning the copy constructor of 
pair, and a couple of pair-like implementation detail types.  The
C++98/03 and 11 standards all specify that the copy constructor of
pair<int, int> is trivial. However as libc++ tracked the draft C++11
standard over the years, this copy constructor became non-trivial, and
then just recently was corrected back to trivial for C++11.

Unfortunately (for libc++1) the Itanium ABI specifies different calling
conventions for trivial and non-trivial copy constructors.  Therefore
currently the C++03 libc++ copy constructor for pair<int, int> is ABI
incompatible with the C++11 libc++ copy constructor for pair<int, int>.
This is Bad(tm).   This patch corrects the situation by making this copy
constructor trivial in C++03 mode as well.

Just in case it is needed for an incomplete C++11 compiler, libc++
retains the ability to support pair with rvalue references, but without
defaulted special members.  However the pair needs non-trivial special
members to implement this special case, (as it did when clang was in
this place a couple of years ago).

During this work a bug was also found and fixed in
is_trivially_constructible.

And there is a minor drive-by fix in <__config> regarding
__type_visibility__.

A test is updated to ensure that the copy constructor of pair<int, int>
is trivial in both C++03 and C++11.  This test will necessarily fail for
a compiler that implements rvalue references but not defaulted special
members.

Marshall Clow 4f44079a2c Apparently, I don't know the difference between 'left' and 'right'. Swap parameters named 'lhs' and 'rhs' so that they correctly refer to the 'left hand side' and 'right hand side' of comparisons. No functionality change. Thanks to Arthur O'Dwyer for pointing this out to me.

Howard Hinnant 525dc284b4 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.

Howard Hinnant 9bf42533b7 Fix bind by making _is_valid_bind_return more robust. It should return false instead of give a compile time error, always. The problem was down in ____mu_return, the version that handles nested bind objects. This fixes http://llvm.org/bugs/show_bug.cgi?id=16343

Howard Hinnant 0125ab809f Remove cv qualifiers from member pointers in the __member_pointer_traits test. This was causing a const-qualified bind result to malfunction. This was a recent regression due to the new use of __member_pointer_traits in restricting the __invokable and __invoke_of tests.
