Casts to remove some warnings. Added casts to remove warnings: BUG=webm:1274 In regards to the safety of these casts they are of two types:- - Normalized bits per (16x16) MB stored in a 32 bit int (This is safe as bits per MB even with << 9 normalization cant overflow 32 bits. Even raw 12 bits hdr source even would only be 29 bits :- (4+4+12+9) and the encoder imposes much stricter limits than this on max bit rate. - Cast as part of variance calculations. There is an internal cast up to 64 bit for the Sum X Sum calculation, but after normalization dividing by the number of points the result will always be <= the SSE value.
