Currently the high-level xor code chunks up all operations into small units for only up to 1 + 4 vectors, and passes it to four different methods. This means the FPU/vector context is entered and left a lot for wide stripes, and a lot of indirect expensive indirect calls are performed. Switch to passing the entire gen_xor request to the low-level ops, and provide a macro to dispatch it to the existing helper. This reduce the number of indirect calls and FPU/vector context switches by a factor approaching nr_stripes / 4, and also reduces source and binary code size.
