Tested it on qemu for arm-none-linux-gnueabi and there is no new
regressions. I am sorry I didn’t mention it when I posted the patch.

Sorry, meant to say vectorization of unaligned loads.

So, does this mean that we get unaligned vector loads
when munaligned-access is on, using vldr instructions ?
