JPEG decoding neon optimization
Bug: 6633342
The idct and color conversion are neon accelerated.
Note, neon accelerations and armv6 assembly accelerations are muturaly
exclusive. When neon is not available, the armv6 assembly is used.

Add SSE optmized IDCT in JPEG decoding for INTEL Atom platform.
ADD SSE optmized IDCT. It makes album2D workload about 18%
faster than jidctfst.c. The major implementation is at
"jidctintelsse.c".

libjpeg: Make both JDCT_IFAST and JDCT_ISLOW use armv6_idct.

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.
