b9a7a45f1f add intrinsics version of SimpleHFilter16NEON()
It's disable for now, because it crashes gcc-4.6.3 during compilation
with -O2 or -O3. It's been tested OK with -O1.

Code is still globally disabled with USE_INTRINSICS, though.

daccbf400d add light filtering NEON intrinsics
disabled for now (but tested OK), thanks to the USE_INTRINSICS #define
We'll activate the code when we're on par with non-intrinsics

c7eb45764f make VP8DspInitNEON() public
this will avoid the "dec_neon.o has no symbol" warning

no change in binary size observed on linux.

255c66b48f Android: only build dec_neon with NEON support
Defining LOCAL_ARM_NEON = true can result in neon instructions being
used in portions unprotected by the cpu check.
This changes defines a WEBP_USE_NEON/WEBP_ANDROID_NEON pair similar to
the SSE2 code and MSVC.

ba503fdac6 NEON TransformOne
As with the loop filter, implementing this with intrinsics is difficult
because we require subscript access for reading and writing 32 bits at a
time.

Approximately 5% decode speed improvement. This could be increased by
exposing TransformOne and rewriting TransformTwo to only handle dual
IDCTs.
