Instead of allocating and embedding certain heap numbers into the code during code assembly, emit dummies but record the allocation requests. Later then, in Assembler::GetCode, allocate the heap numbers and patch the code by replacing the dummies with the actual objects. The RelocInfos for the embedded objects are already recorded correctly when emitting the dummies.
