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.

a911a1e986 Bugfix in integer version of calcCrossCorrAccumulate() 
Using "unsigned long" for "lnorm" variable that was yet made negative in very first step caused incorrect calculation result. Corrected the type to "long".

3d7bf376fd 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

fe15975a21 BPMDetect: Make conversion from size_t to int explicit 
Fixes warning C4267 on MSVC.

This assumes that `beats.size()` should never overflow `int` - if that
could happen, the API should likely be changed to handle it gracefully.
