This patch fixes an RTL aliasing bug with complex types.  The included
testcase triggers the problem for arm-none-linux-gnueabi on 4.1 branch
but not on 4.2 or trunk, but I believe the problem is still present on
trunk although I don't have a test showing it there.

I would suspect that vector-types have the same problem.
