Python & LLVM Extension Modules

This is a quick proof of concept of using the LLVM JIT compiler as Python's extension module loader. This implelentation completely replaces the standard extension module framework, so regular extension modules cannot be loaded. It would not be too difficult to extend the patch to allow loading both LLVM bitcode (.bc) and regular extension (.so) modules.

	"""Property decorator for the `__doc__` attribute.

	Useful for when you want a custom docstring for class instances
	while still showing a generic docstring for the class itself.

	A naive attempt using `@property` generally breaks Sphinx as
	`cls.__doc__` returns the property object itself, and not a string.

	See the documentation for `docstring_property` for an example.
