Currently we find SSE3 and SSE4.1 code mixed togehter along with
generic code in one file. This introduces the risk that the
compiler exidantly mixes SSE4.1 instructions into an SSE3, or
even worse into a generic code path.
This commit splits the SSE3 and SSE4.1 code into separate files
and compiles them with the matching target options.

Convolution is a complex process and we should be able to verify
if computing results change when the implementation is touched.
This commit adds a test program that executes some testcases.
The testcases are crafted in a way that every implmentation
(several different ones for SSE) is executed once. The output
can be compared against the included .ok file.
