After D66007/r369262, if the control flow reaches `if (sym.isUndefined())`, we know: * The relocation is not a link-time constant => symbol is preemptable => Undefined or SharedSymbol * Not an undef weak. * -no-pie. * The symbol type is neither STT_OBJECT nor STT_FUNC. ld.lld --export-dynamic --unresolved-symbols=ignore-all %t.o can satisfy these conditions. Delete the isUndefined() test so that we error `symbol '...' has no type`, because we don't know the type to make the decision to create copy relocation/canonical PLT. llvm-svn: 369271
