Olli Parviainen bf3cec0244 Improvements to help compiler autovectorization ...

Refactored FIRfilter and TDStretch hot-spot routines to help compiler
perform more efficient autovectorization.

Benchmarked:
- 2x/3x improvement in gcc-generated x86 SIMD code execution
  times for SSE2/AVX instruction extensions accordingly, when
  hand-tuned SSE intrinsics were disabled. Hand-tuned SSE code
  still is slightly faster than gcc-produced AVX.
- 2.4x improvement for cumulative ARM NEON tunings when compared to
  previous SoundTouch release.
