f78da3dea6 add LOCAL_CLANG_PREREQ and avoid WORK_AROUND_GCC w/3.8+ 
this results in a 15-20% speedup for lossy decoding on a N5/S6/CM1

01c426f1e7 define WEBP_USE_INTRINSICS w/gcc-4.9+ 
32-bit builds are neutral to slightly faster using ndk r15c on a
N5/S6/CM1

c6d1db4b36 fix Android standalone toolchain build 
add a check for cpu-features.h and rework some of the ifdef's around
android + neon. for android builds with cpu-features enabled the
*_neon.c files will still need to be flagged correctly (with e.g.,
.c.neon in Android.mk) to properly build them.

8e42ba4c80 simplify WEBP_EXTERN macro 
including the type in the macro doesn't bring much benefit to ordering,
current platforms work with a prefix, this would be insufficient if the
attribute needed to follow the function prototype. this form makes it
easier to override on the command line.

9b3aca404d NEON: fix overflow in SSE NxN calculation 
vmlal_u8() is prone to overflow during the accumulation.
There was a mismatch happening at low q mostly. Because in this
case the distortion is important and the accumulated sum was
later than 16bit-unsigned.
