[aarch64-port-dev ] Use an explicit set of registers rather than a bitmap for psh and pop operations.

Hi Andrew,

It looks fine to me. A couple of small points

> Use an explicit set of registers rather than a bitmap for psh and pop operations.

'push' rather than 'psh' in the commit comment

(if this is a pain to fix don't bother)

In class RegSet for consistency I would provide

  RegSet operator-(Register r1)

You have RegSet + Register and RegSet - RegSet. I would be surprised if RegSet - Register did not work for me.

Regards,
Ed.
