[opus] silk_warped_autocorrelation_FIX() NEON optimization
Hi all, I'm sending patch "Optimize silk_warped_autocorrelation_FIX() for ARM NEON" in an separate email. It is based on Tim’s aarch64v8 branch https://git.xiph.org/?p=users/tterribe/opus.git;a=shortlog;h=refs/heads/aarch64v8 Thanks for your comments. Linfeng

[opus] [PATCH] Optimize silk_warped_autocorrelation_FIX() for ARM NEON
Create silk_warped_autocorrelation_FIX_c_opt() which unrolls and parallelizes
input by 8. It has very long prolog and epilog, but this is the cost to get
good speed on this heavily hit function.
This function may be the code base for optimization on different CPUs.
Create ARM NEON intrinsics optimization silk_warped_autocorrelation_FIX_neon().
Create test tests/test_unit_optimization to unit test optimizations.
