None of these new tests actually run by default, because they are
gated to only run for C++2a and the default is gnu++14. That means
they're all skipped as UNSUPPORTED.
(When I add new tests I always try to remember to check the
testsuite/libstdc++.sum file to make sure they are actually running).
The tests need an explicit -std option added via dg-options, which has
to come before the dg-do directive, otherwise the target check still
uses the default options i.e.
// { dg-options "-std=gnu++2a" }
// { dg-do run { target c++2a } }
With that added, most of them start to FAIL:

The errors are all like:

This is because std::remove and std::remove_if are defined in
<bits/stl_algo.h> which is not included.
Could you please fix this ASAP?
