Hi,

This is a short patch set to remove duplication across the ldp/stp
generation code.

In both cases there is no functional change, just a refactor of common
sequences out to their own function, and a replacement of repeated work
with loops.

I think it makes for a cleanup, but I realise this is subjective.

I've bootstrapped the two patches on aarch64-none-linux-gnu with no
issues.

OK?

Thanks,
James
