Move SBRegistry method registrations from SBReproducer.cpp into files declaring the individual APIs, in order to reduce the memory consumption during build and improve maintainability. The current humongous SBRegistry constructor exhausts all memory on a NetBSD system with 4G RAM + 4G swap, therefore making it impossible to build LLDB.
