This patch removes the magic "main" JITDylib from ExecutionEngine. The main JITDylib was created automatically at ExecutionSession construction time, and all subsequently created JITDylibs were added to the main JITDylib's links-against list by default. This saves a couple of lines of boilerplate for simple JIT setups, but this isn't worth introducing magical behavior for. ORCv2 clients should now construct their own main JITDylib using ExecutionSession::createJITDylib and set up its linkages manually using JITDylib::setSearchOrder (or related methods in JITDylib).
