FYI,

It's possible to fix this without adding an architecture method, or 
implementing location expressions (the penny just dropped).  The basic 
problem is the same as for the MIPS - need a custom register area.  Hence:

- define a sequence of nameless cooked ([NUM_REGS .. 
NUM_REGS+NUM_PSEUDO_REGS) range) registers ordered the way stabs would 
like them
- modify the existing stabs_regnum_to_regnum to map the messed up 
registers onto those values
