  Building on the copyi that tege committed the other day, use neon for

I committed the 128 bit version to arm/neon, making it become used for
all Neon capable processors.  I put it there since it is a speedup for
A9 as well as A15, compared to the core code.

Note that this is not yet "Copyright FSF" since we're waiting for FSF to
handle the paperwork.  This is a departure from our previous policy of
waiting out the FSF before comitting contributions.
