Cycles: test code for sse 4.1 kernel and alignment for some vector types. This is mostly work towards enabling the __KERNEL_SSE__ option to start using SIMD operations for vector math operations. This 4.1 kernel performes about 8% faster with that option but overall is still slower than without the option. WITH_CYCLES_OPTIMIZED_KERNEL_SSE41 is the cmake flag for testing this kernel. Alignment of int3, int4, float3, float4 to 16 bytes seems to give a slight 1-2% speedup on tested systems with the current kernel already, so is enabled now.

Code cleanup: some reshuffling of SIMD defines moving more code to util_optimization.h.

Cycles: Deduplicte CPU kernel declaration and definition code Main goal is to make kernel signatures editing easier and less prone to the errors caused by missing function signature update or so. This will also make it easier to add new CPU architectures.
