[PATCH 8/8] Optimize silk_NSQ_del_dec() for ARM NEON
Created corresponding unit test, and the optimization is bit exact with C
function.
This optimization speeds up SILK encoder on NEON as following.
Fixed-point:
Complexity 0-5: 0%
Complexity 6-7: 6%
Complexity 8-9: 10%
Complexity 10: 8%
Got similar results on floating-point.

Int overflow fix not present in tree.
...o pinpoint a single patch to cherry pick to Chromium,
> hence this local fix.
I'm not convinced that using a saturating add here is the correct thing
to do, either (as opposed to, say, multiplying out by the coefficients
individually).
Either way, there are exact analogs of this code in NSQ.c, as well as
all of the SIMD optimizations (x86/NSQ_sse4_1.c and
x86/NSQ_del_dec_sse4_1.c, arm/NSQ_del_dec_neon_intr.c, and
mips/NSQ_del_dec_mipsr1.h). If it is a possible issue in master, the fix
looks incomplete to me, at least.

Transient coding: AAC vs. Vorbis
...out increasing
bitrate that much ? How about temporal noise shaping ?
"Impossible!", you may say. Well, TNS is not a buil-in
Vorbis feature like in AAC. But it doesn't HAVE to.
TNS can be done either by coding the MDCT spectrum by
1) LPC-Filter + quantized LPC residual
OR
2) using an NSQ (noise shaping quantizer)
The AAC format allows method 1. But Method 2 could be done
for both (Vorbis and AAC) without breaking compatibility.
In fact, method 2 is used by MPC in the time domain to
shape the quantization noise within a subband to better
match the masking threshold.
An NSQ applied...

Patch cleaning up Opus x86 intrinsics configury
The attached patch cleans up Opus's x86 intrinsics configury.
It:
* Makes ?enable-intrinsics work with clang and other non-GCC compilers
* Enables RTCD for the floating-point-mode SSE code in Celt.
* Disables use of RTCD in cases where the compiler targets an instruction set by default.
* Enables the SSE4.1 Silk optimizations that apply to the common parts of Silk when Opus is built in
