ENH: Add SIMD versions of negative
NumPy already has SSE2 versions of `negative`. Changes here convert that to universal intrinsics so other architectures can benefit. Previously there was no unroll and SIMD was only used in contiguous cases. We're now unrolling 4x/2x depending on whether destination is contiguous. x86 doesn't perform as well for non-contiguous cases here, so we leave previous implementation / fall back to scalar. Additionally, we've added SIMD versions for ints.
