0211e86a5e Make locales (and transitively, std::endl) work reliably with gcc.
libc++ currently relies on undefined initialization order of global
initializers when using gcc:

1. __start_std_streams in iostream.cpp calls locale:🆔:_init, which assigns
   an id to each locale::facet in an initializer

2. Every facet has a static locale::id id, whose constructor sets the facet's
   id to 0

If 2 runs after 1, it clobbers the facet's assigned consecutive id, causing
exceptions to be thrown when e.g. running code like "cout << endl".

To fix this, let _LIBCPP_CONSTEXPR evaluate to "constexpr" instead of nothing
with gcc.  locale::id's constructor is marked _LIBCPP_CONSTEXPR, which ensures
that it won't get an initializer that could potentially run after the
iostream.cpp initializer. (This remains broken when building with msvc.)

Also switch constexpr-specific code in bitset to use __SIZEOF_SIZE_T__ instead
of __SIZE_WIDTH__, because gcc doesn't define the latter.

Pair-programmed/debugged with Dana Jansens.

83eade6abb No functionality change at this time. I've split _LIBCPP_VISIBLE up into two flags: _LIBCPP_TYPE_VIS and _LIBCPP_FUNC_VIS. This is in preparation for taking advantage of clang's new __type_visibility__ attribute.

11a31d0583 The bitset(unsigned long long) constructor was broken by the constexpr additions only on 32 bit platforms. Fixed. This addresses http://llvm.org/bugs/show_bug.cgi?id=15444.

f867f6326b SFINAE __bit_iterator such that it will only get instantiated with a container that has the nested type __storage_type. This prevents accidental instantiation such as in http://llvm.org/bugs/show_bug.cgi?id=12755. This fixes http://llvm.org/bugs/show_bug.cgi?id=12755.
