UserspaceEmulator: Implement the SSE extension

Browse source 
This almost fully implements the SSE extension, similar to the x87 and
MMX extensions, using a separate class "SoftVPU".

Currently missing are all shadow and exception checks, as well as the
denormals-are-zero and flush-to-zero flags.
Also missing are some integer-SIMD functions.
