8432a1729f Add zero offset checking in SSE2 sub-pixel filter function 
Skip filter at zero offset.

244e2e1451 Write SSSE3 sub-pixel filter function 
1. Process 16 pixels at one time instead of 8.
2. Add check for both xoffset =0 and yoffset=0, which happens
   during motion search.
This change gave encoder 1%~3% performance gain.

d96ba65a23 Add prefetch before variance calculation 
This improved encoding performance by 0.5% (good, speed 1) to
1.5% (good, speed 5).

b862c108dd Overflow of frame error accumulators. 
This fixes an overflow problem in the frame error accumulators.

The overflow condition is extreme but did trigger when Frank B.
coded some high motion interlaced HD content.

The observed effect was a catastrophic  breakdown of the rate
control leading to massive undershoot and poor bit allocation.

All the error values should really be unsigned but I will look at this
separately.

da227b901d Allocate source buffers to be multiples of 16 
Currently, when the video frame width is not multiples of 16, the
source buffer has a stride of non-multiples of 16, which forces
an unaligned load in SAD function and hurts the performance. To
avoid that, this change allocates source buffers to be multiples
of 16.

2debd5b5f7 Improve vp8_sad16x16_sse3 function 
In real-time mode, vp8_sad16x16 function is called heavily in
motion search part. Improvement of this function gives 1.2%
encoding performance gain (real-time mode, tulip clip).
