Allows switchbale filters to be used without mismatch when the
superblock experiment is on.

Also removes a spurious clamping code in decodemv.c which causes
rare encode/decode mismatches.

Refactoring for improved readability - no bitstream or

Previously, the "!=" check is logically incorrect when eob is at 0 and
effective coefficient starting position is 1. This commit should have
no effect on bitstream.

This patch allows use of 8x8 and 4x4 ADST correctly for Intra
16x16 modes and Intra 8x8 modes when the block size selected
is smaller than the prediction mode. Also includes some cleanups
and refactoring.

Rebase.

Given the way mode_context is updated, the benefit of an additional
default is not signficant.

This commit makes sure Y2 entropy coding context is always updated on
every macroblock even there is no Y2 block.

Change-Id: Ie307cfc46526efe55613be39f9f178d2531b56ba

This change included:
1. Aligned reads in vp9_mbloop_filter_vertical_edge function.
Since we actually read 16 bytes, we can align the reads to read
starting at (s - 8) instead of (s - 5).
2. Combined u, v loop filters.
3. Added 8x16 transpose.

This gave 2% decoder performance gain (tulip clip).

This commit removed a couple of redundant data structures in frame
coding contextsm, mode_context and mode_context_a, and changed to
use vp9_mode_contexts only. The switch of the context for different
frame type now relies on the switch of frame coding context between
lfc and lfc_a. This commit also removed a number of memcpy among
these redundant data structure.

Not all segment feature data elements are full-range powers of two, so
there are values that can be encoded that are invalid. Add a new function
to clamp values to the maximum allowed.
