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.

Tuning for ARM NEON
...
Tuning to enable ARM NEON SIMD performance improvements:
- NEON detection in configure file
- Remove manual loop unrolling, gcc autovectorization does better job
without manually unrolled loops.
- Avoid unaligned pointer accesses when using NEON
