Martin Storsjö f637046d31 libavutil: Always use some GCC style attributes on clang Clang normally disguises as GCC (defining __GNUC__), and thus get all the normal GCC specific attributes. Clang can also work as a drop-in replacement for MSVC, and in these cases, it doesn't define __GNUC__, but defines _MSC_VER instead. Even in these setups, it still supports the GCC style attributes, thus use them, especially where there isn't any MSVC specific version, or where the MSVC specific version doesn't work on clang (for DECLARE_ASM_CONST).
