RemoveInvalidLocations was clearing out the m_locations in the breakpoint by hand, and it wasn't also clearing the locations from the address->location map, which confused us when we went to update breakpoint locations. I also made Breakpoint::ModulesChanged check the Location's Section to make sure it hadn't been deleted. This shouldn't strictly be necessary, but if the DynamicLoaderPlugin doesn't do it's job right (I'm looking at you new Darwin DynamicLoader...) then it can end up leaving stale locations on rerun. It doesn't hurt to clean them up here as a backstop. <rdar://problem/36134350> llvm-svn: 322348
