This patch introduces an alternative layout for basic_string which when the string is short, the data pointer will be word-aligned.  It can be activated with -D_LIBCPP_ALTERNATE_STRING_LAYOUT.  These two different layouts (the default and _LIBCPP_ALTERNATE_STRING_LAYOUT) are not ABI compatible with each other.  Once one is chosen for a given platform, it is disruptive to change it.

Make it possible to provide special (linker) flags for the thread tests.
Use it to build & link against libpthread on NetBSD for tests iff they
are testing the thread interface.

The push/pop variant of pragma GCC diagnostic is only supported by Clang
and GCC 4.6 and newer, so protect accordingly.

Stephan Tolksdorf: fixes the issue in the <atomic> header and adds corresponding tests. I've used macros to fall back to a user-provided default constructor if _LIBCPP_HAS_NO_DEFAULTED_FUNCTIONS (though I suspect that there won't be many users defining that macro).

The tests use placement new to check that atomic values get properly zero-initialized. I had to modify the atomic_is_lock_free test, because default initialization of an object of const type 'const A' (aka 'const atomic<int>') requires a user-provided default constructor.
