Justin Bogner 2cfd1fed21 test: Make it possible to opt in to use_clang_verify per test
This modifies the use_clang_verify parameter I added in r217009 to
only apply to tests that specifically ask for it via // USE_VERIFY.
This allows us to incrementally convert tests, but start enjoying the
benefits right away.

Suggested by Eric Fiselier in code review.

Justin Bogner 33a2a2ed1a test: Allow using clang -verify for failures rather than exit 1
Currently, failure tests work by checking that compilation exits 1.
This can lead to tests that fail for the wrong reason, so it'd be
preferable to convert them to check for specific errors.

This adds use_clang_verify parameter that runs failure tests using
clang's -verify flag. I'll convert some tests in subsequent commits,
and once all of the tests are converted we should key this on whether
cxx_under_test is clang.

I've also converted one of the unique.ptr tests, since it's the one
that motivated the idea of using clang -verify when possible in the
review of r216317.

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.
