Update the xor_blocks() prototypes so that the compiler understands that the inputs always refer to distinct regions of memory. This is implied by the existing implementations, as they use different granularities for the load/xor/store loops. With that, we can fix the ARM/Clang version, which refuses to SIMD vectorize otherwise, and throws a spurious warning related to the GCC version being incompatible.
