On macOS, some of the <optional> APIs used by the test are available only
starting on macOS 10.14 when using exceptions. Build the test with
-fno-exceptions so that the test builds on older systems too.

Summary:
The test suite has often unnecessary trailing whitespace, and sometimes
unnecessary trailing lines or a missing final new line. This patch just strips
trailing whitespace/lines and adds missing newlines at the end.

This broke a linux bot which doesn't support -std=c++17. The solution
is to add a decorator to skip these tests on machines with older compilers.

clang recently started diagnosing "exception specification in
declaration does not match previous declaration" errors. Unfortunately
old libc++ versions had a bug, where they violated this rule, which
means that tests using this library version now fail due to build
errors.
Since it was easy to work around the bug by compiling this test with
-fno-exceptions, I do that here. If supporting old libc++ versions
becomes a burden, we'll have to revisit this.

The synthetic child providers for these classes had a type expression that matched
pointers & references to the type, but the Front End only worked on the actual object.
I fixed this by adding a way for the Synthetic Child FrontEnd provider to request dereference,
and then had these formatters use that mode.

On systems where it's not supported.
As far as I understand Linux is the only systems which now ships
with libstdcxx (maybe NetBSD?, but I'm not entirely sure of the
state of lldb on the platform).
We could make this more fine grained looking for the header as
we do for libcxx. This is a little tricky as there's no such
thing as /usr/include/c++/v1, but libstdcxx encodes the version
number in the path (i.e. /usr/include/c++/5.4). I guess we might
match a regex, but it seems fragile to me.

This generalizes a bunch of target-specific tests. MacOS has no
libstdcxx anymore, and neither does FreeBSD (or Windows).

This test was trying to stop at a variety of std::vector calls. It looks like the test
was failing because various inlined std functions left no line table entries for the line that
invoked the inlined function. The author worked around that by undefining _LIBCPP_INLINE_VISIBILITY.
That's an internal libcxx macro, we really shouldn't be playing around with it. Better to just force
ourselves to stop where we want using some other non-inlineable statement. printf seems a good candidate...

In r265181 the test for the NSCFBoolean data formatter was removed.
Later, in r279353 and r279446 a new implementation was provided for the
formatter, which I believe never worked (and this wasn't caught because
the test was never re-enabled).
This commit fixes the bug and re-enables the old test case.

TestLibcxxListLoop - fails because the evil "define private public"
trick does not work with gmodules. The purpose of the test is not to
test debug info parsing so I just mark it as no_debug_info_testcase.
In the long term it may be interesting to write a mock std::list which
will allow us to test bad inputs to data formatters more easily.
TestGModules - seems to be a genuine bug. Filed pr36107 and xfailed.

Stale global module caches cause problems for the bots. The modules
become invalid when clang headers are updated by version control, and
tests which use these modules fail to compile, e.g:
fatal error: file '.../__stddef_max_align_t.h' has been modified since the module file '/var/.../Darwin.pcm' was built
note: please rebuild precompiled header '/var/.../Darwin.pcm'
Eventually we should transition to having just a single module cache to speed
tests up. This patch should be just enough to fix the spurious bot failures due
to stale caches.

Summary:
This flag is on by default for darwin and freebsd, but off for linux.
Without it, clang will sometimes not emit debug info for types like
std::string. Whether it does this, and which tests will fail because of
that depends on the linux distro and c++ library version.
A bunch of tests were already setting these flags manually, but here
instead I take a whole sale approach and enable this flag for all tests.
Any test which does not want to have this flag (right now we have one
such test) can turn it off explicitly via
CFLAGS_EXTRAS+=$(LIMIT_DEBUG_INFO_FLAGS)
This fixes a bunch of data formatter tests on red-hat.

Normal customer devices won't be able to run these tests, we're hoping to get
a public facing bot set up at some point. Both devices pass the testsuite without
any errors or failures.
I have seen some instability with the armv7 test runs, I may submit additional patches
to address this. arm64 looks good.
I'll be watching the bots for the rest of today; if any problems are introduced by
this patch I'll revert it - if anyone sees a problem with their bot that I don't
see, please do the same. I know it's a rather large patch.
One change I had to make specifically for iOS devices was that debugserver can't
create files. There were several tests that launch the inferior process redirecting
its output to a file, then they retrieve the file. They were not trying to test
file redirection in these tests, so I rewrote those to write their output to a file
directly.

There will be some smaller follow-on patches. The changes to tools/lldb-server are
verbose and I'm not thrilled with having to skip all of these tests manually.
There are a few places where I'm making the assumption that "armv7", "armv7k", "arm64"
means it's an ios device, and I need to review & clean these up with an OS check
as well. (Android will show up as "arm" and "aarch64" so by pure luck they shouldn't
cause problems, but it's not an assumption I want to rely on).

The iteration list through the available data formatters was undefined,

Summary:
Displaying the object pointed by the unique_ptr can cause an infinite
recursion when we have a pointer loop so this change stops that
behavior. Additionally it makes the unique_ptr act more like a class

"magic" class.

Summary:
This aims to replace the different decorators we've had on each libc++
test with a single solution. Each libc++ will be assigned to the
"libc++" category and a single central piece of code will decide whether
we are actually able to run libc++ test in the given configuration by
enabling or disabling the category (while giving the user the
opportunity to override this).
I started this effort because I wanted to get libc++ tests running on
android, and none of the existing decorators worked for this use case:
- skipIfGcc - incorrect, we can build libc++ executables on android
with gcc (in fact, after this, we can now do it on linux as well)
- lldbutil.skip_if_library_missing - this checks whether libc++.so is
loaded in the proces, which fails in case of a statically linked
libc++ (this makes copying executables to the remote target easier to
manage).
To make this work I needed to split out the pseudo_barrier code from the
force-included file, as libc++'s atomic does not play well with gcc on
linux, and this made every test fail, even though we need the code only
in the threading tests.
So far, I am only annotating one of the tests with this category. If
this does not break anything, I'll proceed to update the rest.
