Sorry, at LPC atm and have fallen behind. I was still planning to rework
this but I'm aware of other folks at Arm making changes here as well so

Regardless of macros or indirect branches, I was relatively happy with
some of the cleanup that fell out of this series so I'd be keen to land
it either way.
