After change of MI context storage , mi_8x8[]  pointer may be null for
a block outside of image border. The commit changes to access the data
only after validation of mi_row and mi_col.

39c7b01d accidently reverted the row/col initialization, which broke
mv clamps, which is dependent on the sites for valid motion vector
range. This commit fixed the issue.

This commit enables forcing all coefficients zero per transformed
block, when its rate-distortion cost is lower than regular coeff
quantization.

The overall performance improvement (including its parent patch on
calculating rd cost per transformed block) at speed 1:
derf:  0.298%
yt:    0.452%
hd:    0.741%
stdhd: 0.006%

Adds modeled functions to decide the qp for altref frames in constant q
mode similar to other functions in use in bitrate mode.

Also turns on the constrained quality mode (end-usage=2) option which
was turned off before. Basic testing shows the mode works in principle,
to cap bitrate to the target-bitrate specified, while allowing lower
bitrate depending on the cq-level specified. The mode will need to be
improved over time.

Results for constant quality vs bitrate control mode:
derfraw300/fullderfraw: +3.0% at constant quality over bitrate control.
fullstdhdraw: +4.341%
stdhdraw250: +5.361%

This commit makes the rate-distortion optimization loop evaluate
the rd costs of regular quantization and all zero coeffs, per
transformed block. It improves speed 1 compression performance:

derf: 0.245%
yt:   0.515%

For a large partition that consists multiple transformed blocks,
this allows more flexibility to selectively force a portion of
them coded as all zero coeffs, as well be continued in the next
patches.

The sub8x8 blocks has its own motion vector reference scheme. The
mv_pred is only used blocks of sizes 8x8 and above, to find the
starting point for motion search.

This change does not change any coding behavior. It makes the
encoding process slightly faster. (0.5% speed-up for local test on
speed 1.)

Now the same regexp that previously handled cases such as
"ldr r1, [r2, -r3]" also can handle the first operand being omitted
as in "pld [r2, -r3]".

This fixes building vp9_convolve8*neon.asm in thumb mode (and thus,
for Windows Phone as well).

Current x86inc.asm didn't handle 32bit PIC build properly.
TEXTRELs were seen in the library built. The PIC macros from
libvpx's x86_abi_support.asm was used to fix this problem.
The assembly code was modified to use the macros.

Notes: We need this fix in for decoder building. Functions in
encoder will be fixed later.
