In r15-3714-gd3a7302ec5985a I added -Wsystem-headers to the libstdc++ build
flags to help catch problems in the library. This patch takes a different
approach, of disabling the #pragma system_header unless _GLIBCXX_SYSHDR is
defined. As a result, the testsuites will treat them as non-system-headers
to get better warning coverage during regression testing of both gcc and
libstdc++, not just when building the library.
My rationale for the #ifdef instead of just removing the #pragma is the
three G++ tests that want to test libstdc++ system header behavior, so we
need a way to select it.
This doesn't affect installed libraries, as they get their
system-header status from the lookup path. But testsuite_flags
--build-includes gives -I directives rather than -isystem.
This patch doesn't change the headers in config/ because I'm not compiling
with most of them, so won't see any warnings that need fixing. Adjusting
them could happen later, or we can not bother.

As specified in the standard, the predicate for std::erase_if has to be
invocable as non-const with a non-const lvalues argument. Restore
support for predicates that only accept non-const arguments.
It's not strictly nevessary to change it for the set and unordered_set
overloads, because they only give const access to the elements anyway.
I've done it for them too just to keep them all consistent.

This partially reverts commit 561078480ffb5adb68577276c6b23e4ee7b39272.
If we avoid all debug mode checks when erasing elements then we fail to
invalidate safe iterators to the removed elements. This reverts the
recent changes in r12-4083 and r12-4233, restoring the debug checking.

In commit r12-4083 I tried to make the std::erase and std::erase_if
function avoid the unnecessary overhead of safe iterators. It didn't
work, for two reasons. Firstly, for the RB tree containers the
__niter_base function is a no-op (because the iterators aren't
random access) so the safe iterators were still used. Secondly, for the
cases where __niter_base did remove the safe iterator layer, there was
still unnecessary overhead to create a new safe iterator and link it to
the container.
This solves the problem by simply binding a reference to the non-debug
version of the conainer. For normal mode this is a no-op, and for debug
mode it binds a reference to the debug container's base class. That
means the rest of the function operates directly on the non-debug
container, and avoids all checking.
For std::basic_string there's no need to unwrap anything, because we use
std::basic_string directly in debug mode anyway.
