Good point. And the answer seems to be no :/

  ld.lld: .../llvm/lib/Linker/IRMover.cpp:242: llvm::Type *(anonymous namespace)::TypeMapTy::get(llvm::Type *, SmallPtrSet<llvm::StructType *, 8> &): Assertion `!(Pair.first != Ty && Pair.second == Ty) && "mapping to a source type"' failed.

This is with `cmake -DCLANG_ENABLE_BOOTSTRAP=1-DBOOTSTRAP_LLVM_ENABLE_LLD=1-DBOOTSTRAP_LLVM_ENABLE_LTO=1 (...) && ninja stage2`.
