918a2fd726 Use signed variables in the lookahead. 
Wrap around behavior is enforced manually and we use the values in
arithmetic involving negative integers.

36a0c7ffe3 bitreader: remove an unsigned overflow. 
bits_left is in the range [0, 64 (= BD_VALUE_SIZE)] , so the narrowing
conversion should be safe.

6c4007be1c Be explicit about overflow in vpx_variance16x16_sse2. 
The product always fits in uint32_t, but the operands don't.

An optimizing compiler should generate the wraparound code.
(Verified with clang).

ccb894ce73 Remove casts on < 16x16 variance. 
These blocks will never overflow since max sum is +/-255*w*h.

bb1e5b79da Declare the operator== overload for M128A in the global namespace. 
ADL will look this up from the callsite namespace iff it is declared
before the callsite or from the parent namespace of the class type (the
global namespace).

This patch has been tested on MSVS 2015 and clang-3.8.

3ac12aecc5 Optimization for EXT_INTER + OBMC 
Remove the restriction that the neighboring predictor cannot be
used in obmc prediction if it is an interintra or wedgeinterinter
block. The inter predictor of the interintra block, or the first
inter predictor(using LAST or GOLDEN frame) of the wedgeinterinter
block will be exploited in obmc prediction.

size. Passed the bitexact test on clips with different resolutions and
noise levels.
