clang exposes this intrinsic even in 32-bit mode, if targeting >= armv8,
whereas gcc does not, see:

Only manage to warn on non-pointers

Many new features, API still compatible

silk_burg_analysis() could return a slightly negative value on zero
input, which would cause a negative, which the log didn't like.

Without the fix, ubsan would complain about some of the
NULL pointer checks from test_opus_api.

Added proper saturation and rounding

Matches the C code and avoids undefined behaviour

cc.get_define returns str (not bool)

Fixes:
Fetching value of define "__APPLE__" :
../meson.build:316:12: ERROR: Object <[StringHolder] holds [str]: ''> of type str does not support the `bool()` operator.

It was breaking badly for PLC.

-fargan-synthesis not -fargan_synthesis

Used to be disabled for LM==0 because of the unreliable energy in
one-bin bands. Now we just used the max with the previous energy to
stabilize things.

The existing code in vec_avx.h produced
  warning: dereferencing type-punned pointer will break
   strict-aliasing rules
 with gcc 6.4.0.
We already had a macro to work around this within the rules of the
 C standard, but trying to use that here does not get optimized
 into a single MOVD like we were hoping.
Replacing it with memcpy() instead does get optimized correctly,
 but requires switching from a macro to an inline function in order
 to be able to declare a local variable and return a value.
We already have such an inline function in NSQ_del_dec_avx2.c, so
 hoist that out and use it everywhere, and then convert vec_avx.h
 to use it also.

Also, remove -march=native because of AVX512VNNI and valgrind

Fixes regression in 83368e6.
vcgez_s16() is A64-only, but vcge_s16(..., vdup_n_s16(0)) works
everywhere.

Since any value of dQ > 0 will cause the initial quantizer to
 degrade to the format-implied maximum (15) with a sufficient
 number of DRED frames, allow signaling a maximum smaller than 15.
This allows encoders to improve the minimum quality of long DRED
 sequences (at the expense of bitrate) without requiring a constant
 quantizer for all frames (dQ == 0).
