CodeGen: handle llvm.used properly for COFF `llvm.used` contains a list of pointers to named values which the compiler, assembler, and linker are required to treat as if there is a reference that they cannot see. Ensure that the symbols are preserved by adding an explicit `-include` reference to the linker command. llvm-svn: 323017
