For whatever reason ld64 requires that member headers (not the member themselves) should be aligned. The only way to do that is to edit the previous member so that it ends at an aligned boundary. Since modifying data put in an archive is an undesirable property, llvm-ar should only do it when it is absolutely necessary. llvm-svn: 295765
