9f5391ee95 PR libstdc++/88066 use <> for includes not "" 
Using #include "..." to include a header in the same directory fails if
the user compiles with -I-, so always use something like <bits/...> for
internal headers.

I haven't added tests for this, because dg-options adds options to the
end, and the position of -I- matters (if it's at the end then the tests
won't find any headers in the build tree, as they're specified by -I
options earlier in the flags). It's been manually tested though.

da29d2a36e PR libstdc++/67843 set shared_ptr lock policy at build-time 
This resolves a longstanding issue where the lock policy for shared_ptr
reference counting depends on compilation options when the header is
included, so that different -march options can cause ABI changes. For
example, objects compiled with -march=armv7 will use atomics to
synchronize reference counts, and objects compiled with -march=armv5t
will use a mutex. That means the shared_ptr control block will have a
different layout in different objects, causing ODR violations and
undefined behaviour. This was the root cause of PR libstdc++/42734 as
well as PR libstdc++/67843.

The solution is to decide on the lock policy at build time, when
libstdc++ is configured. The configure script checks for the
availability of the necessary atomic built-ins for the target and fixes
that choice permanently. Different -march flags used to compile user
code will not cause changes to the lock policy. This results in an ABI
change for certain compilations, but only where there was already an ABI
incompatibility between the libstdc++.so library and objects built with
an incompatible -march option. In general, this means a more stable ABI
that isn't silently altered when -march flags make addition atomic ops
available.

To force a target to use "atomic" or "mutex" the new configure option
--with-libstdcxx-lock-policy can be used.

In order to turn ODR violations into linker errors, the uses of
shared_ptr in filesystem directory iterators have been replaced
with __shared_ptr, and explicit instantiations are declared. This
ensures that object files using those types cannot link to libstdc++
libs unless they use the same lock policy.

c7790bdbd9 Make ext allocators support heterogeneous equality comparison 
The Allocator requirements include the ability to compare different
specializations of the same allocator class template. This did not work
for __gnu_cxx::new_allocator and other extension allocators.  This patch
replaces the equality operators for those allocators with inline friends
that support heterogeneous comparisons.  (I'm not changing all ext
allocators because some are bit-rotted already).

Additionally, the equality operators for comparing two std::allocator
objects of the same type are now defined as inline friends. Those
overloads don't need to be declared at namespace scope, because they
aren't specified in the standard (but they're needed in this
implementation to avoid ambiguities caused by the extra overloads
defined for the base allocator type).

422a9f7789 PR libstdc++/87544 limit max_size() to PTRDIFF_MAX / sizeof(T) 
The C++17 standard requires the default implementation for
allocator_traits::max_size to return SIZE_MAX / sizeof(value_type).
That causes GCC to warn because the value could be larger than can
sensibly be passed to malloc. This patch changes the new_allocator and
malloc_allocator max_size() members to use PTRDIFF_MAX instead of
SIZE_MAX (and because they define it, the allocator_traits default isn't
used). This also changes vector::max_size to impose a sensible limit
using PTRDIFF_MAX for cases where the value from the allocator or
allocator_traits is not sensible.

3ffa55de60 Rope iterators: don't retain pointers when copied 
Rope iterators sometimes contain pointers to an internal buffer
inside the iterator itself.  When such an iterator is copied, the
copy incorrectly retains pointers to the original.

This patch takes the simple approach of not copying the cached
information when the internal buffer is being used, instead
requiring it to be recomputed when the copied iterator is
dereferenced.  An alternative would be to adjust the pointers so

a6297ab587 Adjust for new empty class parameter passing ABI. 
* include/bits/c++config (_GLIBCXX_BEGIN_NAMESPACE_EMPTY_TYPES,
	_GLIBCXX_END_NAMESPACE_EMPTY_TYPES, _GLIBCXX_ABI_TAG_EMPTY): Define.
	* include/bits/hashtable.h (_Hashtable::_M_emplace): Change signatures
	of functions taking empty structs by value. Add a template parameter
	to overloads without hints. Rename overloads with hints to
	_M_emplace_hint.
	(_Hashtable::_M_erase(true_type, const_iterator),
	_Hashtable::_M_erase(false_type, const_iterator)): Change signatures
	by reordering parameters.
	* include/bits/hashtable_policy.h (_Insert::insert): Adjust to call
	_M_emplace_hint instead of _M_emplace.
	* include/bits/shared_ptr.h (shared_ptr(_Tp1*, _Deleter, _Alloc),
	shared_ptr(nullptr_t, _Deleter, _Alloc)): Use _GLIBCXX_ABI_TAG_EMPTY.
	* include/bits/shared_ptr_base.h (_Sp_counted_deleter, __shared_count,
	__shared_ptr): Likewise.
	* include/bits/stl_algo.h (replace_if): Likewise.
	* include/bits/stl_pair.h (piecewise_construct_t,
	piecewise_construct): Use _GLIBCXX_BEGIN_NAMESPACE_EMPTY_TYPES.
	* include/bits/uses_allocator.h (allocator_arg_t, allocator_arg,
	__uses_alloc0): Likewise.
	* include/ext/pb_ds/assoc_container.hpp (basic_hash_table): Likewise.
	* testsuite/20_util/scoped_allocator/69293_neg.cc: Adjust dg-error.
	* testsuite/20_util/shared_ptr/cons/43820_neg.cc: Likewise.
	* testsuite/20_util/shared_ptr/cons/void_neg.cc: Likewise.
	* testsuite/20_util/uses_allocator/69293_neg.cc: Likewise.
	* testsuite/20_util/uses_allocator/cons_neg.cc: Likewise.
	* testsuite/ext/profile/mutex_extensions_neg.cc: Likewise.
