armv7: celt_pitch_xcorr: Introduce ARM NEON intrinsics
Optimize celt_pitch_xcorr function (for floating point)
using ARM NEON intrinsics for SoCs that have NEON VFP unit.
To enable this optimization, use --enable-intrinsics
configure option.
Compile time and runtime checks are also supported to make sure
this optimization is only enabled when the compiler supports
NEON intrinsics.
