Jonathan Wright 975307775c Neon: Intrinsics impl. of h2v1 & h2v2 fancy upsamp 
The previous AArch32 GAS implementation of h2v1 fancy upsampling has
been removed, since the intrinsics implementation provides the same or
better performance.  There was no previous GAS implementation of h2v2
fancy upsampling, and there was no previous AArch64 GAS implementation
of h2v1 fancy upsampling.
