SSE

[vhirtham]

• Create helper functions to create masks for shuffle intrinsics etc

ToDo

• [x] Put all sse related stuff into base/sse
• [x] Remove SSE from function names and put them into namespace sse
• [x] move all function that do not generalize a sse intrinsic to own header and rename sse.h to intrinsics.h
• [x] Create function to get a single element -> https://www.reddit.com/r/cpp/comments/7qj001/extract_elements_from_m128/
• [x] Create function to write to a single element
• [x] Create mask function for shuffle
• [x] Replace explicit shuffle masks in Transpose header
• [x] Create mask function for blend
• [x] Replace explicit blend masks in Transpose header
• [x] Create mask function for permute functions
• [x] Replace permute explicit masks in Transpose header
• [x] Think about removing 512bit register support, since I can not test it.
• [x] Replace (+rename) SSEGetNumRegisterEntries with numRegisterValues template constant (like alignmentBytes)

Tests

• [x] Test single element getter
• [x] Test single element setter
• [x] Test shuffle masks
• [x] Test blend masks
• [x] Test permute masks
