Preloading import libraries with MSVC

Hi! As discussed earlier[1], there are problems with preloading import libraries when using Microsoft Visual C/C++. This series is a polished version of the previously posted rough cut. However, the first two patches are largely unrelated to the topic, but they help visualize what the meat in the
