Add SSE2 variant of FIR filter

This patch adds an SSE2 variant of the FIR filter, to complement the
existing NEON optimization. This version is written using intrinsics.

Benchmark results: 2.8ns per sample for a 16-tap filter, which is
4x the scalar speed.

Half-rate FIR implementation

This commit is a test implementation of a half-rate FIR structure
(basically a Toom-Cook). It's not bad in the scalar case, but the
benefit is marginal at best in NEON.

FIR filter implementation

This is a FIR filter with NEON speedup. The NEON version has been tested
for accuracy against the scalar one, and there is simple benchmarking
code in place as well.
