libjpeg: Use the new fast-and-accurate IDCT method for ARMv6+ devices. As another AA&N implementation, it runs 9-10% faster than jidctfst.S and 11-15% faster than jidctfst.c. As another IDCT method, it runs 17-20% faster than JDCT_ISLOW method and provides the same accuracy or even better. Change-Id: I81783c310d6dac5aaf84c03a4cf20662f466564c
