Let aom_convolve8_### SIMD implementation support any block width.
Turn on SIMD optimization when interpolation filter types on two
directions are different.

This will reduce 30% of encoding time when dual_filter and ext_interp
both on.

This fixes a rare encode/decode mismatch due to inconsistent
rounding of NEARMV/NEARESTMV vs. ZEROMV motion vectors when both
global motion and ref-mv are enabled.

The new prefixes are
0: 15 bits of state are added to the base state.
10: 22 bits of state are added to the base state.
110: Reserved for super frame marker
111: 29 bits of state are added to the base state.

The likelihood of any final state is proportional to 1 / state. Given a
state range of [2**15, 2 **23) this should save on average 0.4 bits
per serialized final state.

av1_find_mv_refs sets the ALL_ZERO flag when either (a) we don't have
enough candidate MVs, or (b) all candidate MVs are zero. With global
motion enabled, case (b) does not work as intended and causes two
problems: a significant quality decrease for foreman_cif.y4m, and
test failures in *CpuSpeedTest*Screencast*.

This patch skips check (b) when global motion is enabled, fixing
the above bugs.
