Andreas Rheinhardt 91c7710412 avcodec/x86/cfhdencdsp: Avoid unnecessary constants
Up until now, cfhdencdsp used constants consisting
of -1, 1, ...,-1,1 words and 1, -1,...,1,-1 words
for use as constants in pmaddwd. But one can use
the same constants if one shuffles the words in
a dword the opposite order. Similarly for some other
constants. This also allowed to avoid a register in
chfdenc_vert_filter.
