libstdc++: Make _GLIBCXX_CONCEPT_CHECKS more constexpr-friendly
Although most of the old-style "concept checks" are only really usable
with C++98 because they enforce the wrong things, this is a simple
change that makes them a bit more useful for C++14 and up.
* include/bits/boost_concept_check.h (__function_requires): Add
_GLIBCXX14_CONSTEXPR.
* testsuite/25_algorithms/min/concept_checks.cc: New test.
