IRObjectFile provides all the logic for producing mangled names and getting symbols from inline assembly. LTOModule then adds logic for linking specific tasks, like constructing llvm.compiler_user or extracting linker options from the bitcode. The rule of the thumb is that IRObjectFile has the functionality that is needed by both LTO and llvm-ar. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212349 91177308-0d34-0410-b5e6-96231b3b80d8
