[opus] [PATCH 9/9] Optimize silk_inner_prod_aligned_scale() for ARM NEON

[Linfeng Zhang]

Hi Timothy,

Could you please share your make configuration?

I tested on this morning's master with my first 2 patches with the
following configurations and all work fine.

ARM Fixed-point ./configure --build x86_64-unknown-linux-gnu --host
arm-linux-gnueabihf --enable-fixed-point --enable-intrinsics CFLAGS='-O3'
--disable-shared
ARM Floating-Point: ./configure --build x86_64-unknown-linux-gnu --host
arm-linux-gnueabihf --enable-intrinsics CFLAGS='-O3' --disable-shared
X86 Fixed-Point: ./configure --enable-fixed-point --enable-intrinsics
CFLAGS='-O3' --disable-shared
X86 Floating-Point: ./configure --enable-intrinsics CFLAGS='-O3'
--disable-shared

Thanks,
Linfeng
