* Revert "Disable OPENEXR_IMF_HAVE_GCC_INLINE_ASM_AVX when building on arm64 macOS" This reverts commit 67053eb. Signed-off-by: Harry Mallon <hjmallon@gmail.com> * Fix Apple Universal 2 (arm64/x86_64) builds * In these types of builds we want arm64 and x86_64 (with AVX optimisations). However the way cmake works (with `CMAKE_OSX_ARCHITECTURES="arm64;x86_64"` means that we share one OpenEXRConfigInternal.h between both builds. So we have to have OPENEXR_IMF_HAVE_GCC_INLINE_ASM_AVX mean "AVX GCC asm is available if platform is x86", rather than "AVX GCC asm is available". Then we decide on AVX optimisations based on that #define and also the platform defines.

Fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=30291
When DWA data requires DC data, then the compressed DC block size must be non-zero.
Otherwise, potentially large amounts uninitialized memory are processed, which is slow and unpredictable.
