_Alignas is portable than compiler's specific __attribute__. It do
have a limitation, that _Alignas don't support specify aligment on
the declarations of struct (it works for specify alignment on struct
fields),
which only used by avcodec/cavs, and is removed now.
IIRC, _Alignas() is deprecated by C23. Can't we use the proper c11/c23
alignas() instead?
_Alignas is an alternative spelling of alignas in C23 (
https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3220.pdf page 53).
alignas before C23 is a macro defined in header <stdalign.h> ( C17
https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2310.pdf page 197) (
https://en.cppreference.com/w/c/types ).
