Teresa Johnson a66e5da8be Ensure ModuleLinker materializes complete comdat groups ... Summary: The module linker lazy links some "discardable if unused" global values (e.g. linkonce), materializing and linking them only if they are referenced in the module. If a comdat group contains a linkonce member that is not referenced, however, it would not be materialized and linked, leading to an incomplete comdat group. If there are other object files not part of the same LTO link that also define and use that comdat group, the linker may select the incomplete group leading to link time unsats. To solve this, whenever a global value body is linked, make sure we materialize any other members of the same comdat group that are not yet materialized. This ensures they are in the lazy link list and get linked as well. Added new test and adjusted old test to remove parts that didn't make sense with fix.
