lavfi/overlay: correct small error in intersection detection

The image size of the destination image was used to determine if a source
image was positioned outside the destination image, that no intersection
could occur.  Actually for these two cases the size of the source image
has to be used!

avcodec/x86/videodsp: Small speedups in ff_emulated_edge_mc x86 SIMD.

Don't use word-size multiplications if size == 2, and if we're using
SIMD instructions (size >= 8), complete leftover 4byte sets using movd,
not mov. Both of these changes lead to minor speedups.
