Ok, here's how I think we should consider this.

If a DWARF-encoded sequence would consider these as part of the prologue 
(ie they are described as prologue instructions, then the unwinder should 
consider them similarly.  If, however, it considers them as part of the 
function body then the manual unwinder should also do so.

If the latter is correct, then we should also handle storing into the 
stack so that we can also handle frameless functions.
