libstdc++: Avoid unnecessary copies in ranges::min/max [PR112349]
Use a local reference for the (now possibly lifetime extended) result of
*__first so that we copy it only when necessary.
PR libstdc++/112349
libstdc++-v3/ChangeLog:
* include/bits/ranges_algo.h (__min_fn::operator()): Turn local
object __tmp into a reference.
* include/bits/ranges_util.h (__max_fn::operator()): Likewise.
* testsuite/25_algorithms/max/constrained.cc (test04): New test.
* testsuite/25_algorithms/min/constrained.cc (test04): New test.
