[llvm] r232769 - libLTO, llvm-lto, gold: Introduce flag for controlling optimization level.

Seems this is only a problem for our internal implementation and I was being an overly eager good citizen.  :)

All that the API has is a "unsigned optLevel". It is not clear if we should have a size optimization option at this point. All cases that need size optimization should already be converted to function attributes, no?
