libstdc++: Fix compilation with released versions of Clang
Clang 9 supports C++20 via -std=c++2a but doesn't support Concepts, so
several of the new additions related to the Ranges library fail to
compile with -std=c++2a. The new definition of iterator_traits and the
definition of default_sentinel_t are guarded by __cpp_lib_concepts, so
check that in addition to __cplusplus > 201703L.
* include/bits/stl_algobase.h (__lexicographical_compare_aux): Check
__cpp_lib_concepts before using iter_reference_t.
* include/bits/stream_iterator.h (istream_iterator): Check
__cpp_lib_concepts before using default_sentinel_t.
* include/bits/streambuf_iterator.h (istreambuf_iterator): Likewise.
