Implement the proposed resolution of LWG 2708 by moving the _M_options
and _M_pending members out of the recursive_directory_iterator into the
shared _Dir_stack object. Because _Dir_stack is an opaque type, the
member functions that access the _M_options and _M_pending variables
cannot be inline. Move them into the library.
As a drive-by fix, add noexcept to the non-throwing member functions of
recursive_directory_iterator.

This is missing the synchronized_pool_resource and
unsynchronized_pool_resource classes but is otherwise complete.
This is a new implementation, not based on the existing code in
<experimental/memory_resource>, but memory_resource and
polymorphic_allocator ended up looking almost the same anyway.
The constant_init kluge in src/c++17/memory_resource.cc is apparently
due to Richard Smith and ensures that the objects are constructed during
constant initialiation phase and not destroyed (because the
constant_init destructor doesn't destroy the union member and the

The SSO basic_string has a non-standard insert(iterator, initializer_list)
overload, from a C++0x draft. This adds the correct overload, while also
preserving the old one so that the old symbol is still exported from the
library.
The COW basic_string doesn't have any of the C++11 changes to the insert
overloads (they all still have non-const iterator parameters and the
ones that should return an iterator still return void). This doesn't
make any change to the COW string.
