Compiling Unreal Lightmass Fails When Using Visual Studio 2015 Update 2

When attempting to compile Unreal Lightmass in the 4.11 source build, a compiler error pops up when using Visual Studio 2015 Update 2.

Error Message: "d:\unrealengine-release\engine\source\programs\unreallightmass\private\lightmasscore\math\LMMathSSE.h(586): error C3861: '_mm_cvtpu8_ps': identifier not found"

This does not occur if you are using Visual Studio 2015 Update 1.

1. Download Releases branch source (I used Github)
2. Run Setup.bat and GenerateProjectFiles
3. Open the .sln (should be in Visual Studio 2015 Update 2)
4. Attempt to build Unreal Lightmass only

Result: Compile fails with this error message: "d:\unrealengine-release\engine\source\programs\unreallightmass\private\lightmasscore\math\LMMathSSE.h(586): error C3861: '_mm_cvtpu8_ps': identifier not found"

Lightmass fails to compile in VS, results in Swarm failed to kick off.
