23564583a4 Shading: Extend Noise node to other dimenstions. 
This patch extends perlin noise to operate in 1D, 2D, 3D, and 4D
space. The noise code has also been refactored to be more readable.

The Color output and distortion patterns changed, so this patch
breaks backward compatibility. This is due to the fact that we
now use random offsets as noise seeds, as opposed to swizzling
and constants offsets.

2330cadb0f Cycles: Cleanup, don't use strict C prototypes 
Those are more like a legacy of language, which is not
needed in C++.

e5767eaad1 Cycles: Fix missing curve hair when building with GCC-8 in release mode 
Reshuffle cast intrinsics to make XOR to operate on __m128i rather
than on __m128.

Hopefully this does not affect performance.

a8cc0d707e Code refactor: split defines into separate header, changes to SSE type headers. 
I need to use some macros defined in util_simd.h for float3/float4, to emulate
SSE4 instructions on SSE2. But due to issues with order of header includes this
was not possible, this does some refactoring to make it work.

This was already mixed a bit, but the dot belongs there.

8f8b9b58f6 Fix T41066: MSVC + AVX2 kernel causes artifacts in hair render. 
The issue lies in the FMA functions, so disable them on Windows for now.

cd5e1ff74e Cycles Refactor: Add SSE Utility code from Embree for cleaner SSE code. 
This makes the code a bit easier to understand, and might come in handy
if we want to reuse more Embree code.
