Tim Northover 52e76186d3 ARM: refactor .cfi_def_cfa_offset emission. ...

We use to track quite a few "adjusted" offsets through the FrameLowering code
to account for changes in the prologue instructions as we went and allow the
emission of correct CFA annotations. However, we were missing a couple of cases
and the code was almost impenetrable.

It's easier to just add any stack-adjusting instruction to a list and emit them
together.
