Moving functions from vp9_idct_blk to vp9_idct because these functions are
used from both encoder and decoder. Removing duplicated code from
vp9_encodemb.c and reusing existing functions.

Making appropriate memset inside decode_block now.

Remove mode_check_freq and mode_test_hit_counts from VP9_COMP.

The codec should effectively run with motion vector of range (-2048, 2047)
in full pixels, for sequences of 1080p and below. Add assertions to clarify
this behavior.

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%.

near is a key word, changed to use nearmv instead.

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.
