Moving out decode_tokens function calls and adding decode_blocks boolean
variable. We only have to decode if eobtotal > 0, i.e. we have at least one
non-zero coefficient. Also inlining and remove vp9_set_pred_flag_mbskip
function.

The declaration of the bilinear filters specified an alignment clause
in the implementation file but not in the header. This turned out
to be harmless, but it did cause linker warnings to be emitted when
building on Windows.
The (extern) declaration in the header was changed, to match the
declaration in the implementation.

Interleaved the instructions, reduced register dependency, and
prefetched the source data. This improved the decoder speed
by 0.6% - 2%.

Make encoder skip rectangular partition check in speed 1 and above,
when early termination was triggered in partition split.
Thanks Guillaume (gmartres@) for catching this issue.
This change makes bus_cif at 2000kbps speed 1 runtime goes down from
25612ms to 23438ms (about 9% speed-up), at the expense of -0.235%
performance down.

We don't need these functions anymore. The only one which was actually
used is vp9_add_constant_residual_32x32. Addition of
vp9_short_idct32x32_1_add eliminates this single usage. SSE2 optimized
version of vp9_short_idct32x32_1_add will be added in the next patch set,
right now it is only C implementation. Now we have all idct functions
implemented in a consistent manner.

The code now takes into account temporal and spatial
information to determine the partition size range, but the
frequency counts have been removed.
The net effect is similar in quality but about 10% faster.

This patch deletes the variance based speed three partitioning.
Speed 3 now uses the same partitioning method as speed 2
but with some stricter conditions.
The speed and quality are now somewhere between speeds 2 and 4
whereas before it was worse in both than speed 4.
