Andreas Rheinhardt	59a9d65e0d	avcodec/adxenc: Avoid undefined left shift of negative numbers Replace "((a << shift) + b) >> shift" by "a + (b >> shift)". This avoids a left shift which also happens to trigger undefined behaviour in case "a" is negative. This affected the FATE-tests acodec-adpcm-adx and acodec-adpcm-adx-trellis; it also fixes ticket #8008.
