David Nadlinger d47bdb234a gen: Use single ldc.register_dso function for both module ctor/dtor
This reduces the size of a statically linked Phobos-based
Hello World by 11 kB on Linux x86_64.

Also creates a header file for gen/module.cpp, which has been
renamed to "modules" such as not to conflict with the frontend
header file.
