Has gone latent again on trunk, but confirmed that the code here is both broken
and unnecessarily complex.  Testing a fix.

I'm seeing similar at:
 https://bugs.launchpad.net/gcc/+bug/809446

and:
 https://bugs.launchpad.net/gcc-linaro/+bug/885393

but it's a bit random.

Richard Earnshaw was looking at this recently.  I'll ping him.

Looks like the problem is with neon_movv4si. 

My patch enabled the use of quad-word vectors by default, the test doesn't fail
with double-words.
