[libc++][AIX] Add scripts and config for building with the libcxx CI infrastructure
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).
