6e80079a28 avcodec: increase AV_INPUT_BUFFER_PADDING_SIZE to 64 
AVX-512 support has been introduced, and even if no functions currently
use zmm registers (able to load as much as 64 bytes of consecutive data
per instruction), they will be added eventually.

fbdd78fa3e avcodec/fft: fix INTERL macro on 3dnow 
The commit b7c16a3f2c ("x86: fft: Port to
cpuflags") breaks the opus decoder in ffmpeg when compiling for 3dnow. The
output is audible, but there's a lot of noise.

The reason for the breakage is that the commit unintentionally changed the
INTERL macro so that it is empty when compiling for 3dnow. This patch
fixes it.

43171a2a73 Fix missing used attribute for inline assembly variables 
Variables used in inline assembly need to be marked with attribute((used)).
Static constants already were, via the define of DECLARE_ASM_CONST.
But DECLARE_ALIGNED does not add this attribute, and some of the variables
defined with it are const only used in inline assembly, and therefore
appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks
variables as used.

This change makes FFMPEG work with Clang's ThinLTO.

43dab86bcd opus_pvq_search: Restore the proper use of conditional define and simplify the function name suffix handling. 
Using named define properly documents the code paths.
It also avoids passing additional numbered arguments through
multiple levels of macro templates.

The suffix handling is done by concatenation, like in
other asm functions and avoid having two separate
"cglobal" defines.

3c99523a28 opus_pvq_search: split functions into exactness and only use the exact if its faster 
This splits the asm function into exact and non-exact version. The exact
version is as fast or faster on newer CPUs (which EXTERNAL_AVX_FAST describes
well) whilst the non-exact version is faster than the exact on older CPUs.

Also fixes yasm compilation which doesn't accept !cpuflags(avx) syntax.
