PR libstdc++/86751 default assignment operators for std::pair
The solution for PR 77537 causes ambiguities due to the extra copy
assignment operator taking a __nonesuch_no_braces parameter. By making
the base class non-assignable we don't need the extra deleted overload
in std::pair. The copy assignment operator will be implicitly deleted
(and the move assignment operator not declared) as needed. Without the
additional user-provided operator in std::pair the ambiguity is avoided.
PR libstdc++/86751
* include/bits/stl_pair.h (__pair_base): New class with deleted copy
assignment operator.
(pair): Derive from __pair_base.
(pair::operator=): Remove deleted overload.
* python/libstdcxx/v6/printers.py (StdPairPrinter): New pretty printer
so that new base class isn't shown in GDB.
* testsuite/20_util/pair/86751.cc: New test.
* testsuite/20_util/pair/ref_assign.cc: New test.
