3c6dc743aa Fix a bug in create_s16x4_neon() 
This bug exposes when 2nd argument is negative, and the higher 32 bits
would be all 1s.

93166c5e51 neon: vpx_quantize_b_32x32 
With skip block the neon is about twice as fast as C.

The neon has no shortcut for coeff < zbin so it always takes the
same amount of time. Even if the C can take the shortcut, it is over
twice as fast in neon. If it can't, that gap increases to over 10x.
