    • Fix AIX test failure due to replacement operator delete · 39f901e9 
      On AIX the sized delete defined in the library will call the non-sized
delete defined in the library, not the replacement version defined in
the test file. By also replacing sized delete we make the test pass
everywhere.

	* testsuite/20_util/allocator/1.cc: Add sized delete, which fixes a
	failure on AIX.

    • PR libstdc++/90281 Fix string conversions for filesystem::path · 26b1320e 
      Fix several bugs in the encoding conversions for filesystem::path that
prevent conversion of Unicode characters outside the Basic Multilingual
Plane, and prevent returning basic_string specializations with
alternative allocator types.

The std::codecvt_utf8 class template is not suitable for UTF-16
conversions because it uses UCS-2 instead. For conversions between UTF-8
and UTF-16 either std::codecvt<C, char, mbstate> or
codecvt_utf8_utf16<C> must be used.

The __str_codecvt_in and __str_codecvt_out utilities do not
return false on a partial conversion (e.g. for invalid or incomplete
Unicode input). Add new helpers that treat partial conversions as
errors, and use them for all filesystem::path conversions.

    • Simplify node ownership in _Hashtable members · b0c849fa 
      Introduce an RAII type to manage nodes in unordered containers while
they are being inserted. If the caller always owns a node until it is
inserted, then the insertion functions don't need to deallocate on
failure. This allows a FIXME in the node re-insertion API to be removed.

Also change extract(const key_type&) to not call extract(const_iterator)
anymore.  This avoids looping through the bucket nodes again to find the
node before the one being extracted.
