Summary: Our python version of the SB API has (the python equivalent of) operator bool, but the C++ version doesn't. This is because our python operators are added by modify-python-lldb.py, which performs postprocessing on the swig-generated interface files. In this patch, I add the "operator bool" to all SB classes which have an IsValid method (which is the same logic used by modify-python-lldb.py). This way, we make the two interfaces more constent, and it allows us to rely on swig's automatic syntesis of python __nonzero__ methods instead of doing manual fixups.
