vp8cx : bestsad declared and initialized incorrectly.

bestsad should be an int initialized to INT_MAX.  The optimized
SAD function expects a signed value for bestsad to use for comparison
and early loop termination.  When no match is made, which is
determined by a comparison of bestsad to INT_MAX, INT_MAX is returned.
