This includes: - Adding new LlvmType called LMStructP that represents an unpacked struct (this is necessary since LLVM's instructions the llvm.sadd.with.overflow.* return an unpacked struct). - Modifications to LlvmCodeGen.CodeGen to generate the LLVM instructions for the primops. - Modifications to StgCmmPrim to actually use those three instructions if we use the LLVM backend (so far they were only used for NCG).
