d6c3260db7 reduce_args_tactic: make it aware that 'a + const' may be a unique value in bv theory 
it allows us to remove UFs that are of the form f(a + 1), f(a + 2), etc..

a3e0eae9ec Move CMakeLists.txt files (other than the one in the repository root) 
and the cmake directory into a new directory ``contrib/cmake`` that
mirrors the directory structure of the root. This is a comprimise
between me and Christoph Wintersteiger that was suggested by Arie
Gurfinkel that allows the CMake build system to live in the Z3
repository but not impact the Z3 developers that want to avoid the CMake
build system. The build system will not work in its new location
and a bootstrap script will soon be provided that allows a developer
to copy the files back to their correct location.

849c16c4fc Don't try to remove the CMAKE_INSTALL_PREFIX from the 
``python_install_dir``. The implementation was broken because
we would strip off ``/usr`` and then install into
``/lib/python-3.5/site-packages``. We could remove the leading slash
to make sure we install into the CMAKE_INSTALL_PREFIX but doing so
seems unnecessarily complicated given that DESTDIR still seems to
be respected even when given absolute paths to the CMake ``install()``.
