Remove sixtap/bilinear 4x4 neon implementations These implementations rely on casting the pointers to load the data. Clang implemented optimizations which automatically add alignment hints to such loads. The 4x4 filters do not guarantee the necessary alignment so the resulting assembly is broken. https://llvm.org/bugs/show_bug.cgi?id=24421 BUG=webm:817 BUG=webm:892 Change-Id: I608885299f1f86ff83653b65e0e40d0ae87fb3fe
