In an effort to fix concrete variables referencing abstract origins where the concrete variable preceeds the first inlined usage, the addition of attributes such as name, file, etc will be delayed until the end of the module (to wait to see if any inlined instances have occurred, thus necessitating an abstract definition that the concrete definition should also reference). These test cases don't actually need to care about this ordering of attributes, so update them to be more resilient to such changes coming in the near future. llvm-svn: 210940
