e15371061d lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bump 
They are not properly namespaced and not intended for public use.

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.

e9a68b0316 x86: prores: templatize 10 bits simple_idct 
This should be reused for a generic simple_idct10 function.
Requires a bit of trickery to declare common constants in C.
