In the new-style testing configurations, we were hardcoding paths to the
`include` and `lib` directories, which was incorrect but always went
unnoticed because the hardcoded values always happened to match the
actual value.
When using new-style configs with the bootstrapping build, this falls
appart -- and we never noticed this because the bootstrapping build was
still using old style configs.
This patch removes the %{install} substitution, which makes it too
tempting to hardcode installation paths, and it also switches the
bootstrapping build to actually using new-style configs like we
always intended to do.

Using -isystem marks the headers as system headers, which means that we
don't actually get all the warnings that we'd normally get if we included
the headers as user headers.
The goal of the test suite is normally to mirror as closely as possible
how users would use the library. Technically, this change goes against
that philosophy, since users should be using `-isystem` (if they ever
need to specify the libc++ path explicitly, which should be a rare
occurence). However, I believe fishing out additional warnings from
the headers provides more value, hence this change. Ideally, we'd be
able to still use `-isystem`, but instruct Clang to still emit warnings
from the libc++ headers (e.g. we could tell Clang to emit warnings in
any file inside `<...>/usr/include/c++/v1`).

We added one for libc++ recently, and this patch adds one for libc++abi.
Also, as a fly-by fix, include older libunwind dylibs in the testing of
libc++ and libc++abi, which fixes some issues related to running
back-deployment tests on newer systems.

This allows cross-testing (by setting LIBCXX_EXECUTOR to point
to ssh.py) without making an entirely new test config file.
Implicitly, this also fixes quoting of the python executable name
(which is quoted in test/CMakeLists.txt).

This initial change adds the AIX configuration to run-buildbot, an AIX
CMake cache file, and appropriate compiler and linker flags for testing
AIX to the lit "from scratch" configuration files. Either of the 32-bit or 64-bit configurations
can be built by setting `OBJECT_MODE` in the build environment (as is
typical for AIX).

I came across an issue where since we build the library for Apple with
the install name directory being /usr/lib, which means that if we don't
run the tests with DYLD_LIBRARY_PATH, we'll end up loading the
system-provided libc++abi when running the tests. That wreaks havoc.
Instead of fixing it in the legacy config file, this commit introduces
an Apple libc++abi config file that does the right thing.
