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()``.

9b48b5ca83 When building with OpenMP make sure libz3 passes extra linker 
flags. This is necessary for libz3 to be usable from the Python
bindings when libz3 is built with gcc or clang.

fb449517e3 Teach the CMake build system to build and install the python bindings 
The new ``BUILD_PYTHON_BINDINGS`` option (off by default) will enable
building the bindings and the new ``INSTALL_PYTHON_BINDINGS`` option
enables installing them.

f6e946443e Made emission of the API module files `api_log_macros.h`, 
``api_log_macros.cpp`` and ``api_commands.cpp`` optional in
``update_api.py``. This is required to implement support for
building and installing Z3's API bindings with CMake.

c9e3332019 Teach the CMake build system to generate the module exports 
file ``api_dll.def`` and append the necessary flag to the linker
when using MSVC. The MSVC build with CMake now succeeds and both
the ``c_example`` and ``cpp_example`` work :)

beb21126e2 Move where the Z3 API header files to be scanned by the Python scripts 
is declared out of ``src/api/CMakeLists.txt`` and into
``src/CMakeLists.txt``. We will need this list to generate the
``api_dll.def`` module definition file for MSVC. Whilst I'm here
also fix a stray use of ``USES_TERMINAL`` in ``add_custom_command()``.

ca6c41e411 Don't append ${OpenMP_CXX_FLAGS} to Z3_DEPENDENT_LIBS. This is wrong 
because this is passed to ``target_link_libraries()``. It just so
happens that ``target_link_libraries()`` will interpret arguments
starting with a dash as a flag to pass to the linker (i.e. in this
case ``-fopenmp``). However in the case of MSVC that flag is ``/openmp``
which is the interpreted as a file path which will lead to a linker
failure later because the linker can't find the file ``\openmp.obj``.
