Finalized the SSE2 optimizations for the matched filter in AEC3

The SSE2 optimizations of the filter core in the matched
filter was only half-done. This CL finalizes those.

In particular:
-It adds finalization of updating of the filter.
-It removes the manual loop unrolling in order to reduce and
simplify the code.

Note that the changes pass the bitexactness tests in an
external AEC3 test suite, and the test
MatchedFilter.TestOptimizations succeed.
