This can be useful for clients constructing custom JIT stacks: If the C API for your custom stack exposes API to obtain a reference to an object layer (e.g. LLVMOrcLLJITGetObjLinkingLayer) then the newly added LLVMOrcObjectLayerAddObjectFile and LLVMOrcObjectLayerAddObjectFileWithRT functions can be used to add objects directly to that layer.
