If the codec was configured with --enable-internal-stats,
a seg fault would occur. This patch fixes the problem.

Adds backward adaptation and differential forward updates of switchable
interpolation filter probabilities. Also adds some cosmetic cleanups
and minor fixes on mv_ref probabilities.
derfraw300: +0.353% (with most coming from switchable interp changes)

Condition the existing zbin boost logic for gf/altf mode to temporal layers==1,
since gf/altf reference frames are used in temporal layers as reference frames.

This commit makes operations of the superblock intra coding rate
distortion optimization consistent with those used in the encoding
process. Given the test prediction mode and transform size, the rd
optimizer encodes and reconstructs each transformed block of the
superblock consecutively, then computes the total rate-distortion
costs accosicated with the current superblock to select the coding
decisions.
It achieves coding performance gains:
derf 0.353%
yt 1.111%

Fixes an issue where newer versions of GCC would try to compile the
visual studio inline assembly.
Fixes issue #571

Enable iterative motion search for compound inter-inter prediction
of block sizes 4x4/4x8/8x4 only when best coding quality is selected.
The iterative motion search provides about 0.1% gains for derf and
stdhd at this point, at the expense of longer runtime.

Restrict get_matching_candidate() to considering
mvs at 8x8 and larger sizes for last frame case.
This is to reduce the HW load of using vectors down
to the 4x4 level from the previous frame.

This speed 1 - uses variance threshold stolen from static-thresh
to determine split. Any superblock with greater than the variance
set by static thresh * quantizer index squared is split. In addition
transform size is set to largest size less than or equal to partition
size, sub pixel filter is set to normal, and only 12 modes are used
at all.
