In certain hardware configuration, where mmx code is enabled and
other simd (sse2/sse3) disabled, lacking of this emms caused invalid
internal stats outputs.

Except zrun_zbin_boost, 15 AC values are the same for all other
parameters. Removed unneccessary calculation.

The code had a number of constructs like (condition)?1:0,
which is redundant with C's semantics. In the cases where a boolean
operator was used in the condition, simply remove the ternary part.
Otherwise adjust the surrounding expression to remove the condition
(eg, for rounding up. See pickinter.c and rdopt.c)

Make bilinearfilter_arm.c compiled only when HAVE_ARMV6, as its definitions
are v6 only. This is normally not a problem for static builds as the file
is elided at link time, but this was not being done properly for the
--enable-shared --enable-pic build.

This commit extends the number of Q steps to 256 from 128.
The q_trans[] array has been altered to distribute available Q index values
(using the current 64 steps available as input parameters) evenly across the
available range. This is coupled with the fact that each Q step where possible
now equates to a fixed % change in the quantizer. This may want refinement
later especially in terms of the granularity at the high quality end but is a
reasonable starting point.

High Q end extended a little.
Some clean up.
Slightly better on SSIM, Slightly worse on PSNR over derf set.

Added code to support 256 index steps instead of 128 but disabled for now.
Replace hard wired table vp8cx_base_skip_false_prob[128]
Observed Qindex problem with setting minimum loop filter value.
(Experiment code using real Q in place but for now just returning 0. This has a big
beneficial effect on some clips, particularly waterfall which shows 5% ssim gain)

Merged multi-resolution motion estimation with regular motion
estimation function in order to remove duplicated part. This
caused slight changes in multi-resulotion encoder quality &
performance.

The total_stats, this_frame_stats, and total_left_stats structures
were previously create by a heap allocation, despite being of fixed
size. These structures were allocated and deallocated during
{de,}allocate_compressor_data, which is reinvoked whenever the frame
size changes. Unfortunately, this clobbers the total_stats and
total_left_stats data.
Historically, these were variable size at one time, due to the first
pass motion map, which necessitated their being created by a unique
heap allocation. However, this bug with the total_stats being
clobbered has probably been present since that initial implementation.
These structures are instead moved to be stored within the struct
twopass_rc directly, rather than being heap allocated separately.

mode_info_context is padded with an additional column of data, so
mode_info_stride should be used to move between rows rather than
mb_cols.

These functions are now used by the encoder.
This is WIP with the goal of creating a common idct/add for
the encoder and decoder. A boost of 1.8% was seen for
the HD rt test clip used.
[Tero] Added needed changes to ARM side.

Both encoder & decoder were using mb_cols to
offset from one row of MODE_INFO structures to the next
when they should have been using mode_info_stride.
Fixing this in both encoder and decoder gives around
a 3KB size saving and 0.025dB PSNR improvement on the one
720P clip I tried.
(Also removed "index" which was being updated but not used)

While doing motion search on a macroblock, we usually call
vp8_find_near_mvs once per reference frame. Actually, for
different reference frames, the only difference in calculating
these near_mvs is they may have different sign_bias, which
causes a sign change in resulting near_mvs. In this change, we
only do find_near_mvs for the first reference frame. For other
reference frames, only need to adjust the near_mvs according to
that reference frame's sign_bias value.

The fast-path for skipped MBs was not correctly respecting the
block type during update of the coefficient counts. Extracted

Removed a couple more fixed tables for the extended quantizer experiment
that depend on QINDEX_RANGE.

Previously, Y-adaptive UV intra coding only enabled on key frames in
UVINTRA experiment. This commit enabled the same coding for inter
frames, so the encoding of UV intra modes are consistent cross all
frame types. Tests on derf set showed a very small overall gain around
.04%:
http://www.corp.google.com/~yaowu/no_crawl/interUVintra.html
The gain looks to be reasonable given inta coded MBs is only a
small portion of MBs in inter frames.

update_mbgraph_frame_stats used xd->mode_info_context
before it had been setup, resulting in potentially
random accesses of uninitialized memory.
This fix allocates a local MODE_INFO structure to hold
the data generated in the function.
