The 20_util/scoped_allocator/69293_neg.cc test was failing in C++2a mode because the expected static_assert text wasn't matched. The code is still ill-formed in C++2a, but uses the new __uses_alloc_args function and so fails a different static_assert. This patch adds the same string to the new static_assert, so the test passes. Now that G++ allows concepts to be declared without 'bool' we can use the correct C++2a syntax for the _Std_pair concept used to constrain the uses-allocator construction utilities. Also add a new test to verify that pmr::polymorphic_allocator correctly performs recursive uses-allocator construction for nested pairs in C++2a. * include/std/memory (__uses_alloc_args): Add string-literal to static_assert, to match the one in __uses_alloc. [__cpp_concepts] (_Std_pair): Use C++2a syntax for concept. * testsuite/20_util/polymorphic_allocator/construct_c++2a.cc: Check for recursive uses-allocator construction of nested pairs. * testsuite/20_util/scoped_allocator/construct_pair_c++2a.cc:: Add comment.
