The horizontal 10bit MC SSE2 functions are currently duplicated:
They exist both in ordinary form as well as with a "sse2_cache64"
suffix. A comment in ff_h264qpel_init_x86() indicates that this
is due to older processors not liking accesses that cross cache
lines, yet these functions are identical to the non-cache64
functions (apart from the unavoidable changes in the rip-offset).
The only difference between these functions and the ordinary ones
are that the cache64 ones are created via a special form of the
INIT_XMM macro: "INIT_XMM sse2, cache64". This affects the name
and apparently defines cpuflags_cache64, yet nothing checks for
this, so both versions are identical. So remove the cache64 ones
and treat the remaining ones like ordinary SSE2 functions.
