Chris Bieneman d3199f5ed2 [CMake] Initial support for LLDB.framework 
Summary:
This patch adds a CMake option LLDB_BUILD_FRAMEWORK, which builds libLLDB as a macOS framework instead of as a *nix shared library.

With this patch any LLDB executable that has the INCLUDE_IN_FRAMEWORK option set will be built into the Framework's resources directory, and a symlink to the exeuctable will be placed under the build directory's bin folder. Creating the symlinks allows users to run commands from the build directory without altering the workflow.

The framework generated by this patch passes the LLDB test suite, but has not been tested beyond that. It is not expected to be fully ready to ship, but it is a first step.

With this patch binaries that are placed inside the framework aren't being properly installed. Fixing that would increase the patch size significantly, so I'd like to do that in a follow-up.

""" Python SWIG post process script for each language
--------------------------------------------------------------------------
File: finishSwigPythonLLDB.py
Overview: Python script(s) to post process SWIG Python C++ Script
Bridge wrapper code on the Windows/LINUX/OSX platform.
The Python scripts are equivalent to the shell script (.sh)
files.
For the Python script interpreter (external to liblldb) to
be able to import and use the lldb module, there must be
two files, lldb.py and _lldb.so, that it can find. lldb.py
is generated by SWIG at the same time it generates the C++
file. _lldb.so is actually a symlink file that points to
the LLDB shared library/framework.
The Python script interpreter needs to be able to
automatically find these two files. On Darwin systems it
searches in the LLDB.framework, as well as in all the normal
Python search paths. On non-Darwin systems these files will
need to be put some place where Python will find them.
This shell script creates the _lldb.so symlink in the
appropriate place, and copies the lldb.py (and
embedded_interpreter.py) file to the correct directory.
Gotchas: Python debug complied pythonXX_d.lib is required for SWIG
to build correct LLDBWrapperPython.cpp in order for Visual
Studio to compile successfully. The release version of the
Python lib will not work (20/12/2013).
LLDB (dir) CMakeLists.txt uses windows environmental
variables $PYTHON_INCLUDE and $PYTHON_LIB to locate
Python files required for the build.

(optional) put the lldb.py file it generated from running
SWIG.
--prefix Is the root directory used to determine where
(optional) third-party modules for scripting languages should
be installed. Where non-Darwin systems want to put
the .py and .so files so that Python can find them
automatically. Python install directory.
--lldbLibDir The name of the directory containing liblldb.so.
(optional) "lib" by default.
