92b5800277 avcodec/x86/pixblockdsp: Remove obsolete MMX functions
x64 always has MMX, MMXEXT, SSE and SSE2 and this means
that some functions for MMX, MMXEXT and 3dnow are always
overridden by other functions (unless one e.g. explicitly
disables SSE2) for x64. So given that the only systems that
benefit from these functions are truely ancient 32bit x86s
they are removed.

353aecbb28 pixblockdsp, avdct: Add get_pixels_unaligned
Use this in vf_spp.c, where the get_pixels operation is done on
unaligned source addresses.

Hook up the x86 (mmx and sse) versions of get_pixels to this
function pointer, as those implementations seem to support unaligned
use.

This fixes fate-filter-spp on armv7.

de452e5037 pixblockdsp: Change type of stride parameters to ptrdiff_t
This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.

Also adjust parameter names to be "stride" everywhere.
