libstdc++: Test for feature test macros more accurately
...
Tests which check for feature test macros should use the no_pch option,
so that we're really testing for the definition being in the intended
header, and not just testing that it's present in <bits/stdc++.h> (which
includes all the standard headers and so defines all the macros).

libstdc++: Optimise GCD algorithms
...
The current std::gcd and std::chrono::duration::_S_gcd algorithms are
both recursive. This is potentially expensive to evaluate in constant
expressions, because each level of recursion makes a new copy of the
function to evaluate. The maximum number of steps is bounded
(proportional to the number of decimal digits in the smaller value) and
so unlikely to exceed the limit for constexpr nesting, but the memory
usage is still suboptimal. By using an iterative algorithm we avoid
that compile-time cost. Because looping in constexpr functions is not
allowed until C++14, we need to keep the recursive implementation in
duration::_S_gcd for C++11 mode.
For std::gcd we can also optimise runtime performance by using the
binary GCD algorithm.
libstdc++-v3/ChangeLog:
* include/std/chrono (duration::_S_gcd): Use iterative algorithm
for C++14 and later.
* include/std/numeric (__detail::__gcd): Replace recursive
Euclidean algorithm with iterative version of binary GCD algorithm.
* testsuite/26_numerics/gcd/1.cc: Test additional inputs.
* testsuite/26_numerics/gcd/gcd_neg.cc: Adjust dg-error lines.
* testsuite/26_numerics/lcm/lcm_neg.cc: Likewise.
* testsuite/experimental/numeric/gcd.cc: Test additional inputs.
* testsuite/26_numerics/gcd/2.cc: New test.
