Additional configure check for gcc SSE intrinsics
It turned out that if a CPU supports SSE the already existing test for SSE assembly instructions always passes. However, the compilation of gcc SSE intrinic instructions might nevertheless fail if gcc is not called with one of the options "-msse3", "-msse4" , "-msse4.1", "-msse4.2", "-mavx", or "-mavx2"! Obviously gcc does still not consider SSE as a standard on X86_64 Intel CPUs. An additional configure test has been introduced, which test for gcc intrinsic sse instructions. If this test fails, the corresponding kernels are switched off.
