Add a flag to lib/Linker (and `llvm-link`) to override linkage rules. When set, the functions in the source module *always* replace those in the destination module. The `llvm-link` option is `-override=abc.ll`. All the "regular" modules are loaded and linked first, followed by the `-override` modules. This is useful for debugging workflows where some subset of the module (e.g., a single function) is extracted into a separate file where it's optimized differently, before being merged back in.
