libstdc++: Only use std::compare_three_way when concepts are supported
Clang now supports three-way comparisons. That causes both overloads of
std::lexicographical_compare_three_way to be defined, but the second one
uses std::compare_three_way which depends on concepts. Clang does not
yet support concepts, so the second overload should also depend on
__cpp_lib_concepts.
* include/bits/stl_algobase.h (lexicographical_compare_three_way):
Only define four-argument overload when __cpp_lib_concepts is defined.
