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.

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.

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