Delete unused global aliases with internal linkage. In fact this also deletes those with linkonce linkage, however this is currently dead because for the moment aliases aren't allowed to have this linkage type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61742 91177308-0d34-0410-b5e6-96231b3b80d8 2009-01-05 20:37:33 +00:00			`; RUN: llvm-as < %s \| opt -globaldce \| llvm-dis \| not grep @D`
