Instead of a new plugin for stack initialization[1], this improves structleak to handle initialization of all variable types. Since the instrumentation happens at a different point, the "switch" statement changes from the earlier posting[2] are no longer needed. As before, this also introduces a stack initialization regression testing module to validate various kinds of stack variable usage vs compiler instrumentation for initialization. See the individual patches for more details.
