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. Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org>
