c45c472e1b Cycles: SSE optimization for line segments/ribbons hair 
Gives ~11% speedup for hair.blend, ~10% for koro_final.blend

Also extract few common subexpressions in hair calculation.

7808360c5f Cycles: fix crash in SSE hair and half-floats on x86+vc2008 
MSVC 2008 ignores alignement attribute when assigning from unaligned
float4 vector, returned from other function. Now Cycles uses unaligned
loads instead of casts for win32 in x86 mode.

47c5898fa1 Cycles: SSE for Voronoi textures (targeted for Haswell CPUs) 
Gives up to 15% speedup scenes with voronoi-based textures (up to 25% with volumes) on Haswell. The performance change for other CPUs is much smaller: 1-2%.

1578b55c27 Cycles: Move SIMD utility functions into its own file. 
Recently added SSE macros for noise texture can be moved here as well, but I leave this for later.
