    JNT_COMP: Refactor code · f78632e0
    Cheng Chen authored
    The refactoring serves two purposes:
    1. Separate code paths for jnt_comp and original compound average
    computation. It provides function interface for jnt_comp while leaving
    original compound average computation unchanged. In near future, SIMD
    functions can be added for jnt_comp using the interface.
    
    2. Previous implementation uses a hack on second_pred. But it may cause
    segmentation fault when the test clip is small. As reported in Issue
    944. This refactoring removes hacking and make it possible to address
    the seg fault problem in the future.
