PR libstdc++/89090 avoid C++17 features in C++11/C++14 code
Although GCC and Clang both allow these features pre-C++17 in system
headers, Clang does issue warnings with -Wsystem-headers. It can also
complicate bisection and/or testcase reduction if # line markers are
stripped, because the code won't be known to come from system headers.
PR libstdc++/89090
* include/bits/stl_uninitialized.h (__relocate_a_1): Make unused
parameter unnamed. Add message to static assertion.
* include/bits/vector.tcc (vector::reserve, vector::_M_realloc_insert)
(vector::_M_default_append): Use _GLIBCXX17_CONSTEXPR for if constexpr
in C++11 code.
