thread_stack__process() is used to create call paths for database export. Improve the handling of trace begin / end to allow for a trace that ends in a call. Previously, the Intel PT decoder would indicate begin / end by a branch from / to zero. That hides useful information, in particular when a trace ends with a call. Before remedying that, enhance the thread stack so that it identifies the trace end by the flag instead of by ip == 0.
