The step that sums three input samples could potentially cause the
intermediate result go beyond 16 bit limit, when operating as the
second 1-D transform. This commit fixes the issue.

Overall change (using dual buffer scheme for superblocks of both inter
and intra modes) reduces speed 2 runtime:
bluesky_1080p at 6000kbps:   263553ms -> 257441ms
riverbed_1080p at 8000kbps:  233230ms -> 225308ms.

Match any whitespace instead of individual spaces. The macro
definitions in vp9/common/arm/neon/vp9_short_idct32x32_1_add_neon.asm
triggered this and treated spaces as arguments leading to lines like:
$8vld1$8.$88$8           {$8q8$8}, [$$89$8], $$8stride$8

As Jim suggested, 1D array was used to store filter levels instead
of 2D array. This used shift_y in setup_mask directly, and saved
few cycles.
