Mimimal implementation that I could use to demonstrate speedups. Will add inline comments where I think this is not satisfying yet. Apart from that, what do you think? Do you have proposals for improvements?

Originally I wanted a real ThinLTOLayer with a proper ThinLTOLayerMaterializationUnit, integration with llvm::orc::lookup(), etc. So far I failed to get the SymbolFlags handling right, when passing the MaterializationResponsibility down to the underlying IRLayer. Would be great to fix that and upstream it, but it's no hurry.
