Switching from mi_{width, height}_log2 and b_{width, height}_log2 to
num_8x8_blocks_{wide, high} and num_4x4_blocks_{wide, high}. Removing
redundant code, adding const.

This commit resolved a mis-alignment issue in compound inter-inter
prediction of sub8x8. This patch follows solution from dkovalev@.

In subpel_avg_variance functions, code similar to the following

punpkldq m2, [addr]

actually reads 8 bytes. For functions that are supposed to work on
buffers only have less 8 bytes a line, this caused valgrind error
of reading uninitialized memory.

vp9_setup_interp_filters before each inter block decoding, it is not
necessary to call it just before the whole frame decoding.

after encoder's patch.
