gdbarch implements its own registry-like approach. This patch changes it to instead use registry.h. It's a rather large patch but largely uninteresting -- it's mostly a straightforward conversion from the old approach to the new one. The main benefit of this change is that it introduces type safety to the gdbarch registry. It also removes a bunch of code. One possible drawback is that, previously, the gdbarch registry differentiated between pre- and post-initialization setup. This doesn't seem very important to me, though.
