andrew@webrtc.org 818c9f9e14 replace inline assembly WebRtcNsx_SynthesisUpdateNeon by intrinsics. ...

The modification only uses the unique part of the synthesis_update
function. Pass byte to byte conformance test both on ARMv7 and ARMv8,
and the single function performance is similar with original assembly
version on different platforms (if not specified, the code is compiled
by GCC 4.6):
