    Fix segfault with loop-restoration on x86. · befcc425
    David Barker authored
    The WienerInfo struct requires a 16-byte alignment on x86,
    since it contains filter coefficients which are loaded using
    SSE aligned load instructions. But on 32-bit x86, the default
    alignment of aom_malloc/aom_realloc is only 8 bytes, leading
    to occasional segfaults.
    
    To fix this, rather than using aom_realloc to resize WienerInfo
    structures, we always free and re-allocate them using aom_memalign
