65b375e798 Cycles: Move non-vectorized bitscan() to util
This way we can use bitscan() from both vectorized and non-vectorized
code, which applies to both kernel and host code.

08fbc303e1 Cycles: Resolve compilation error of avx2 kernel with certain compilers
It was redefined macro happening with Clang 3.6 here.

5ff132182d Cycles: Code cleanup, spaces around keywords
This inconsistency drove me totally crazy, it's really confusing
when it's inconsistent especially when you work on both Cycles and
Blender sides.

Shouldn;t cause merge PITA, it's whitespace changes only, Git should
be able to merge it nicely.

ee36e75b85 Cleanup: Fix Cycles Apache header.
This was already mixed a bit, but the dot belongs there.

3144ae2c34 Cycles: Slight modification to the previous commit
This way util_simd.cpp would not require modifications
if/when SSE2 is suddenly supported on 32bit platforms.

This also allowed to unleash some issues with util_simd.h
related on the fact that there size_t and int are actually
the same types.

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.

Differential Revision: https://developer.blender.org/D482

Code by Brecht, with fixes by Lockal, Sergey and myself.

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.

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%.

Recently added SSE macros for noise texture can be moved here as well, but I leave this for later.
