Adding missed parenthesis around boolean expressions. Bitstream is changed.
Regenerating test vectors.

This function is actually called from set_offsets which is called right
before vp9_read_mode_info.

Super basic conversion from the other implementations. Any changes to
one should be trivial to copy over keep in sync.

this was never fleshed out in the context of VP8, for which it was
added. for VP9 it has no meaning.

Implements some of the helper functions more efficiently with
lookups rathers than branches. Modeling function is consolidated
to reduce some computations.
Also merged the two enums BLOCK_SIZE_TYPES and BlockSize into
one because there is no need to keep them separate (even though
the semantics are a little different).
No bitstream or output change.
About 0.5% speedup

For some reason iOS builds take a really long time to sort this
function out.
It's not used anywhere so remove it.

Adding segmentation struct to vp9_seg_common.h. Struct members are from
macroblockd and VP9Common structs. Moving segmentation related constants
and enums to vp9_seg_common.h.

Independent horizontal and vertical implementations.
Requires that blocks be built from 4x4 and [xy]_step_q4 == 16
6-10% improvement. CIF improved the least.

The function encode_block is called only by inter-prediction modes,
hence removing the transform type branching there.

This patch is in experimental but was not merged into master.
This patch swaps ptrs instead of copying and uses the
last show_frame flag instead of setting the entire buffer
to zero.

With sf->auto_mv_step_size on it is questionable
whether sf->reduce_first_step_size is worthwhile.
At speed 2 it was not having a big impact.
Even at speed 2 sf->optimize_coefficients = 0 is not
having a big speed imapct so for now I have moved it
down into a higher speed setting.

Enable SSE2 4x4 inverse ADST/DCT transform. The runtime goes from
292 cycles down to 89 cycles. Running bus_cif at 2000 kbps, the
overall runtime of speed 0 goes from 301s to 295s (2% speed-up).
