[PATCH][AArch64] Use std::swap instead of manually swapping in aarch64-ldpstp.md

[Kyrill Tkachov]

Hi all,

This patch makes use of std::swap in every peephole2 of 
aarch64-ldp-stp.md instead of manually swapping rtxen.
No functional change, just a cleanup.
Bootstrapped and tested on aarch64.

I'm proposing this for next stage1 together with the other AArch64 patch 
that
moves a couple of places of aarch64.c to use std::swap
(https://gcc.gnu.org/ml/gcc-patches/2014-11/msg01426.html)

Thanks,
Kyrill
