This commit adds a new mode to call injection. If the runtime.debugPinner function is available in the target executable it obtains a pinner by calling it and then uses it to pin the pointers in the results of call injection. This allows the code for call injection to be refactored to execute the calls in the normal order, since it doesn't need to be concerned with having space on the target's memory to store intermediate values.
