make symbols internal when possible
Add a post-processing pass to `trans` that converts symbols from external to internal when possible. Translation with multiple compilation units initially makes most symbols external, since it is not clear when translating a definition whether that symbol will need to be accessed from another compilation unit. This final pass internalizes symbols that are not reachable from other crates and not referenced from other compilation units, so that LLVM can perform more aggressive optimizations on those symbols.
